world is your oyster once you have a uv map.
without one you can't bake normals, ao etc...
texture import is vital but not from the outset. main purpose is to get this out as a minimum viable product and then let the users dictate it's dev.
You're absolutelly right!
Also, my concerns are really not aiming at my current workflow as I'm using substance and as you say the only thing I need is an UV map and doing it with sketchup tools.
Basically, I need only what you have right now!
But I just cannot help pestering you, it's a way to feel involved already. Will it also be easy to select some edges and rotate them or edit them somehow so they get absolutelly vertical or horizontal?
That would help a lot in some architectural workflows and I cannot do it with blender (I know it's pbcac... don't shove that on me!
) -
looks amazing....

Will it?
It can do it already
Align to top,bottom, left and right. Pin points too. And Relax.

I'm relaxed... will wait for it calmly now...
-
I'm calm as well...
But I do want to see more of this... -
question on the video...
the shell of the car was mostly green. The areas around the lights were red while an area opposite was blue - This indicates the checker material is being squashed or stretched? red squashed blue stretched. So will WrapR be able to fix this?
how? - by moving the vertices around individually? I don't know much about UV mapping.... -
Also - will we be able to get models into games engines?
a second UV channel was needed for Unreal for example. -
I don't believe you need the second UV channel. At least I was able to export to UE without it... The only problem I faced was 64+ materials on my model. It doesn't handle so many and I also haven't managed to actually work inside UE as I hadn't the time to dable with it.
-
....actually i think the second UV channel is now created by default by UE if the model doesn't have one...I just remembered.
I ran into problems where some of my model would be fine in UE for a while then after a 'lighting' build everything went crazy - supposedly due to the lack of the second uv channel. anyway, like you, finding time to try and experiment is hard to find. -
If you want to use lightmaps in Unreal, you need a second UV channel. If you want to use only dynamic lights, you don't.
Unreal can create a second UV channel from Sketchup's texture channel. It basically makes a copy of the texture UV's, and re-shuffles all the individual UV islands so they fit in a 0-1 space.
Most textures in SketchUp have UV coords outside that 0-1 space so Unreal takes a bit time for that.
Problem is though, this only works for simple geometry. For more complex or curved elements (furniture for instance) the UVs in SketchUp are not nicely stitched together but all loose islands and all over the place. This results in a large lightmap with all kinds of tiny little islands and lots of wasted space. These lightmaps take more time to calculate and never look really well - even at higher resolutions.For those elements, make your own lightmap UVs in Blender is your best option.
-
kaas, but if the original textures are UV unwrapped onto one of these organic models, the lighmap problem persists?
I mean if we have something unwrapped the second UV channel to lightmap convertion works well?

If you have nicely layout uvs (like in the image) AND the export to obj or fbx doesn't mess them up, I expect Unreal will most likely be able to re-use them easily.

Nice... It's not such a big deal with hard face modelling right?

You're right... though it also relates to the usefulness of Wrap-R...
-
This video shows how you can mark seams in SketchUp anf it will be unwrapped in Wrap-r when it imports....
...You can also see UV shells getting flipped.
Next is live syncing in SU so you don't need to save-close-open-save-close-open...

Saving multiple UV maps per mesh is on the roadmap.
Whoaa... Hold on!
Are you developing that prior to release or after release?

prior to....
so, technically, would one then be able to save bump maps, etc. (all related to specfic textures) in the sketchup file?
initially I thought this tool would only really benefit organic modeling, but it seems as though it may be of good use for all, especially if you want to contain all your texture info in one place... or am I understanding this wrong?
