Just upgraded to the newest VRay (v1.48.66) and was wondering:

 -Is there anyway to alphabetize the materials in the VRay material editor?

Quick bath model and render I did today. C&C's welcome.

I'm thinking about looking more into Vray. How's the learning curve been? What sort of experience do you have with other renderers and which one's have you used?

Good job on the rendering.

-Brodie

Lol, hey brodie, sorry for the delayed response. I haven't really used any other rendering engine before this. I used Mental Ray briefly in school but Vray is my main rendering tool. The learning curve isn't too bad. I've been using it now for about 4+ months and you can already see the result.

Thank you all for the C&C's! I will work on the glass and fire textures and the fireplace also. thakns again!

Epic render

I think the fire needs work. I wouldnt have the faintest idea how to do it.
Is the fire image an emissive material?

Hey Holmes,

The fire was actually done post render in photoshop. I was going to render it as an emissive material but got lazy and just did it in Pshop. Maybe next series of renderings I will create an emissive material (and even better yet, attempt to animate the fire for an animation, that is if, someone wants to give me direction on how to do that).

I'm still waiting on some more changes to this project, because the client actually made some minor adjustments to the floorplan, this fireplace being part of the new sheme.

Thanks!

Project we're working on at work. Vray w/ some post pShop. C&C welcome!

Contact ASGVis support with the model in question. Have them have a look at it.

thanks thom, I'll go ahead and do that.

I had that issue as well some time ago and ended up loading the default.visopt (render settings panel), saving, closing and reopening the file.
That solved it for me.
If it would not work, try to copy /paste in place the whole content into a new file and set things up from scratch....

I hope this helps,

Cheers,
Kwistenbiebel

Kwistenbiebel,

We will try that. We have actually never tried any of the provided default visopts with vray, we have always just ran our own settings. The thing is that, we think this model is cursed, Lol, because have cut this model to pieces. Removing things that we don't need, simply getting the just the bare bones. We have cut and paste into new models at least 3 times and everytime there is always something wrong with the rendering or we just get a bugsplat.

Hi all,

We are having some troubles at our office with black squares appearing in the "rendering final image" phase. We have never had this issue before and now all of a sudden we have been getting black squares appearing in the middle of our renders and shortly after sketchup crashes.

Does anyone know what might be causing this and how we can go about fixing it.

Thank you!
Steve

lol bit nice for a first go. im sure thats not your first render! but very photo real, nice just colour banding is a bit of an issue thats all!

Thanks guys, VRay rules. You have to play around with it to perfect (just like everything). I like this renderer compared to others because of its realistic shadows.

I know, this is not my 1st render ever, more like my 500th. I'm just being goofy, because I've noticed that other people have done the same thing!

p.s. Oli, you know any tips to prevent the color banding?

@thomthom said:

What's your Adaptive Amount in the DMC sampler?

.85.... that's the best setting right?

Thanks everyone, I ended up using the omni spot technique talked about on ASGVis forums. The blotchiness was, once again, caused by low subdvsns and samples in the irradiance map.

Still more tweaking needed but heading in the right direction.

HAPPY NEW YEAR!

Emission materials are not supposed to be used as main light source. Do you still get these artefacts if you hide the objects with emissive materials?

Hey Thom, I'm not trying to use emissive objects as light sources, but simply for the visual effect. I tried rendering without the emissive objects and the blotchy effect did not occur. What I'm trying to figure out is if this is coming from the emissive object or because of my reflective materials close by the emissive object.

Anyone know the reasoning for this non-sense? Please enlighten me. We have to finish these renders for a client and start animations pronto. So any insight will help! Thanks again for looking.

p.s. All the lights are objects with emissive properties. Can lights have a chrome like material inside the can and my "artichoke" lamp was grouped, so it did not show above the table. I thought that if I unchecked "trace reflections" under the Chrome material it would help, but does not cure the problem.

Thanks!

VRay for Sketchup, Post in Photoshop.

Hi

I emailed ASGvis about this. They said ............. .........

It is possible to do what is called a "fly-through" animation using SketchUp (and therefore V-Ray) in which only the camera moves. This is not a supported function of V-Ray but something that SketchUp does that we can enhance using our render engine. You can find tons of information about animation on our free forums. Here is a link to just one of the many postings about this:
http://forum.asgvis.com/index.php?topic=4324.0

However I am having trouble accessing the ASGvis site! So Ihope it can help. Please let me know.

Guy

Thanks Guy for the insight. I will have to take a look at this. I am new to rendering fly-through's and stuff and i will probably end up doing them in 3DS Max, but I just wanted to see if there was any easy way to accomplish this with sketchUp, because I love that you don't have to switch from program to program.

I rendered two scenes as an "animation" from the vRay options and saved the jpg's. I tried then combining and creating them into a video in Sony Vegas but the thing is, is that it isn't arranging the jpgs as 30frames/sec. its doing like 1 frame every 4 seconds and I have no idea how to tell it to do it 30/sec.

Hope someone has a simple solution,

Thanks again!
Steve

Hi all, I'm in the process of learning animations and what not. Here at our company we want to put together fly-throughs of our projects for the clients to see and also to put on our website. Can someone lay down in simple steps the process one needs to do to create a video?

Under the output menu in the vray options there is an animation box, which I have checked, but when I render it just does all the frames and then ends up with nothing. Do I need to save all the renders and then combine them into a video? If so, how would I do that?

Please give me some insight!!!

Thanks,

Steve

Anyone know how to achieve soft shadows with vray? (vray for su)

Solo, the way that I achieve softer shadows, is I would just up the shadow subdivisions from say 8 to like 32. That always seems to work for me! You can do that for any type of light in vRay for SU. As for the sun, you can do the same and I normally like to have the size multiplier at around 3, instead of 8-12 like the other guy said, but thats just me. Hope this helps.

Well Captain, when pictures don't render for me, normally it's because they are grouped. I don't know if vRay or just my vRay but, it does not usually render objects that art grouped, only components or not at all. As for the electronic emissive screens. I would try to apply the image as a texture 1st on the object (ungrouped) and then create an emissive material with that image in the emissive map as a 'bitmap'.

Secondly, I would check in further with the <a href="http://www.scribd.com/doc/1845643/VRay-for-SketchUp-Manual">vRay for SU Manual</a>.

Hope this helps and good luck

Yes, V-Ray samples dark areas less.
Is it suppose to be so dark?

If note, I'd adjust the camera exposure - if you're using the Physical Camera.

Thanks Thomthom for the exposure advice, I will check that out. Should I just up the samples then to cure the darker area blotchy effect? That area to the right of the scene is not supposed to be that dark. There are plenty of windows from that side of the room to illuminate the room in the actual house, so I'm trying to keep it consistent in the render.

Chango, I will have to try your tip with larger plane lights. The only thing, when you use 'no decay' does that take away from a more realistic render?

I was thinking about using point lights under the recessed can lights instead of small plane lights, I think that might give me a brighter render.

Looks good man. I would put a image in the background outside of the doors to give the model a bit of context. Also, maybe implant some magazines or posters and what not, but overall lighting is good, textures are on. Great start!
