Vray for Sketchup - Problems with materials
Hi good folks! Not sure if this is the correct forum or not, but I'm trying out Vray for Sketchup and I can't help to notice that is seems as though Sketchup's materials and Vray's materials are complete separated? When I apply a Vray-material to a sketchup-model, it doesn't show in Sketchup. Only when I render, which makes it a bit hard to tell what's actually going on without having to render everything.
Now, I also noticed that, once I've applied a Vray material to a section of a model, then I can't seam to get it off. I've tried to select "apply material" and select "none", but it doesn't do anything.Also, I've tried to use a Vray glass material on a portion of the model, a clean straight face actually. But it doesn't look like glass at all, it's completely distorted reflections from the back side and when it looks as though the backside of the face is completely black! Why?
This is a single faced wall, no thickness on the wall at all. So the material should be applied to the both sides right? -
How to avoid moire-effects?
Hi, I've noticed that I get alot of moirรจ-effects with my tiled textures in Sketchup. Is there a way of avoiding this?

RE: Texturing - Would this be a smart approach?
Well, at first I'm creating the city to be used in Google Earth. And it's all done using Sketchup. But at a later date, I'm eventually going to use the assets in a game engine. But that's pretty far ahead in time.
During the work with Sketchup and Google Earth, some buildings will probably be repeated. But just a few since this is city that's evolved from scratch about a thousand years ago. Meaning that the buildings aren't even mathematical correct at all.
So I thought I'd use a smart way of texturing to save memory and thus, increasing performance that way. That's why I'm tiling as many textures as possible. The models will be quite simplified and won't have a high polycount at all. At a later date, I'm going to take pictures of the buildings and use CrazyBump to create the bump-maps etc. I've already done some testing on this and the results is very nice indeed! -
RE: Texturing - Would this be a smart approach?
Wait what? You say you create a more detailed versjon of a model. Then create a render of it from one side and then cut out the side from the render and then use that as a texture? Can't image that it would look very good though? I mean, sure it looks pretty nice in Google Earth as far as I can tell from the screenshot you posted. But still, I'm modeling a whole city and these models should be used in a game engine at a later date. Which means that I need to be able to use these models as much as possible to ease the production pipeline. And of course, we're gonna use multiple textures such as diffuse, bump and specular maps. This sure is a tough one. Considering that the method I end of going for would have an effect on the project at this later date. Need to figure out the smartest way of doing this.
@ Modelhead, do you have any examples of how it end up looking after you export to a game engine? And you never ever have any problems with the exported geometry? Wow, that's amazing. I've tried exporting to 3ds and obj and the result is always a huge mess.

RE: Texturing - Would this be a smart approach?
Ok, nice to know that I'm on the right track atleast!
Do you have any experience with exporting these models into other 3d apps? What do you think would happen around these windows and lines? -
Texturing - Would this be a smart approach?
Hi! I'm beginning a huge project which includes loads of models of of buildings which will, eventually, form a whole city. I'm currently more at the planning stage but have done some models and some textures. And I'm wondering what would be the best way of texturing these buildingds? It's first and foremost meant to be used in Google Earth but will a while later be imported into a game engine. So I probably need to think about that too.
Anyway, I guess that tilable textures would be the way to go right? Now, concidering windows and stuff, I've done it this way right now:

Is this a stupid way of doing it? I've drawn lines around the edges of the window to make sure it blends the best way I can. And many of the textures will be reused on other buildings since this would be the most effective. I was thinking about cutting out the windows from a picture I've taken and have everything around the window itself be transparent. But this didn't work. So I did it this way. Would this get a huge performance hit or something?
What would probably happen to this model when/if I export it to be used in a game engine? -
RE: Sketchup, UVs and cleaning models for export
Hmm, I see.. I get what you're saying. But then I don'ยจt think I understand exactly how other 3d apps really work. Can't believe that the model get completely useless after exporting from Sketchup. The export features ARE there, so it must be possible to clean up the model after exporting somehow.
In Bodypaint, I tried to convert all geometry to ngons and all triangles was lost. But after working on the UVmap a while, I got this error that several faces was shared by a polygon. And a few other glitches in the model. But other than that, it works just fine.Could it be possible to write a rubyscript that scans for these errors? And then fix them?

RE: Sketchup, UVs and cleaning models for export
Ok, another question now. After talking to some experienced modelers who's taken a look at one of my Sketchup models of a window in Cinema 4D, they say that the model basically is a huge mess. Meaning, there are triangles everywhere and some ngons too. They recommended me to remodel it in Cinema. But I really don't want to do that! Sketchup is so easy to understand! Why can't the development team do some more work on the export-feature and make some good export-features instead= So that it won't be a big mess?

RE: Sketchup, UVs and cleaning models for export
Ok, just thought I'd edit this post.
I now understand how the UVs work and how I can arrange parts to make sure there are no UV overlapping, which is the main thing I need to focus on. Where each UV-part actually are would actually be quite irrelevant since I would be painting textures directly onto the model in Bodypaint or Zbrush. Therefore I don't need to worry about where the UV actually is. I just have to make sure it's projected properly and we're good to go! I think I've finally found a workflow that can actually work!
My back actually shivered a bit just thinking I possibly would need to learn how to model in another 3d app than Sketchup!:PWill post results in this thread from now on

RE: Sketchup, UVs and cleaning models for export
Wait a minute, just found out something. Ok, so I selected all windows on my model in Zbrush (the components) and clicked "explode" and then I removed all components while the windows were still intact on the model. And then I selected everything in my model and chose Intersect --> Intersect with model.
This took a while, but now when i imported this OBJ-file into BodyPaint, there's only one single object! Hooray! Could this actually mean that modeling in Skethcup doesn't need to be a pain later on? Certainly would seem that way. Now, I just need to figure out how to layout my UV-map to make it behave a bit like this:See, the edges are somewhat connected together in order to have seamless textures. Oddly, my UV map seem to be not connected at all, where each little part and bit is assigned it's own separated space. Should be able to connect the ones I want, just don't know how yet. Or if there's a more automated way of doing it.

RE: Sketchup, UVs and cleaning models for export
Sorry, I don't quite understand what you mean here. I'm not really trying to render anything, I'm just trying to wrap my head around this whole exporting thing, what format to use and which settings to use when exporting from Sketchup etc. Anyhow, I just created a window just now in Sketchup and exported this to OBJ and imported it into Bodypaint. Then I exported it to 3ds and imported it again and the whole model became one object. I think this might be the right approach. It certainly made the UVs alot better! At least I'm not painting on several layers of UV now.
This is the window in Sketchup
And here's what it looks like in BodyPaint 3d at the moment:
Still, there's something not quite right. But that may be just the use of Bodypaint I guess. I've painted the edge on the window with a white color. And on the UV-map it seems as though it's been separated into several individual squares (well, two triangles put together to form a square)
But in general, seems as though Sketchup relly sucks at exporting and that you can get various results everytime you try. But it seems as though Sketchup creates a new object everytime something is copied. For instance, I created a window and made this into a component. Then I copied that component and never though more about that. But now, I see that since all the copies of that window is identical, all texture I apply to one window gets transferred to the other windows as well. Surely there seems to be some sort of connection here.
Edit: Rightclick on the last image and press "view image" to see the entire image. Looks like these boards have some sort of max width set on pictures.

Sketchup, UVs and cleaning models for export
Ok, I love Sketchup and it's userfriendly interface. And it's real easy to model buildings.
But I'm having real trouble with exporting my models to external softwares like Zbrush, Bodypaint etc.
First of all, I've tried different settings for export and how found that some basic settings keep my model intact, but Unfold3D says that there are errors in my mesh and UVs come out all scrambled and stuff. Also, trying to paint on the model in Bodypaint creates odd results. It seems as though my model has several "layers" of UV or something, cause when I try to paint on the model, I simultaneously paint on other places on the model too. I guess this has something to do with Unfold3D giving me the error message and stuff.I created a thread about this is c3dcafe.com:
http://www.c4dcafe.com/ipb/index.php?showtopic=34981Now, I don't know all there is to know about 3dmodels, in fact, I don't know much at all!
What about UVs, do they always matter? Do I NEED to set up UV correctly to be able to texture my model?
It's building by the way, very simple.Also, what settings to you use when exporting Sketchup-models to other 3d apps? I've heard something about "reversed faces", but my model doesn't seem to have any. What is your best workflow when exporting models?
Do I need to setup materials? Do I need to do explode all components from my model or should I create a component of the entire model so that it becomes one component? What should I do?! Thanx in advance.
