Still slogging away at learning the lighting controls. also having a bit of an issue with the mapping of textures (see lamp on left). all in good time. Still have a lot of modeling to do, so I hope I can get the texture issue figured out.  I've seen couple of threads about the issues, so I guess I'l have to do some more research.interiors.png

Looking great so far!

There are a number of plugins for UV mapping, the latest and greatest being WrapR, but it’s Windows only I believe.

Podium sometimes has trouble interpreting the texture mapping on rounded/triangulated objects, even if it looks OK in SketchUp.  TBH, I'm not sure precisely what causes it.... Podium can usually read UVs for imported models accurately, because a lot of our Podium Browser components are modeled outside SketchUp and imported.  But sometimes you get cases like this where the texture mapping appears correct in the viewport, and ends up distorted in the render.

Try exploding the lamp all the way down until it's completely un-grouped, then see if it will render the texture correctly.

If that doesn't work, either attach the lamp component here, or send it to support@cadalog-inc.com, and I should be able to fix the UV map.

Yea, I tried the exploded component trick once but it didn't seem to work. I'll take a look at the model and give it another try. Thanks.

Yeah I didn't think it would... what does it look like in the viewport?

We have a Skimp license, which is an import/export and polygon reduction plugin.  It also has a very convenient ability to repair broken UV maps almost automatically.  What we do is use the reduction tool, but set it to 100% -- the geometry ends up unchanged, but it automatically remaps the texture.  I'd say this works about 95% of the time.

If you can't figure it out, I'm happy to run it through Skimp real quick.

skpDD 2020-05-17 22553700000_1800.pngWell, I'm back hacking away at SUPodium. First render in over a month. Been giving the VRAY 30 day free trial at try for the heck of it. The UV mapping in SUPodium still doesn't work correctly in a few cases. In VRAY there re five settings which usually solve any mapping issues.Untitled58a_1800.png This is a VRAY image of a similar scene. Client has a really ridiculously long shag in his dining area, so it was nice to be able to use the VRAY fur to accomplish that task. Any chance that SUPodium will get a feature like that in the future?

You can do this already in Podium using the Fur plugin, it creates geometry for the actual carpet pile.

We are going to implement instancing, which will reduce the render time significantly.

Act image has different elements which are more realistic - lighting is quite different, it's an interesting comparison!

You probably ought to use the interior High preset in Podium for this.

Yea, I forgot about the fur plugin for Sketchup. Here's a quick stab at it. Needs some work around the edges. I beveled the edges so the fur would not stick straight out. Couldn't control it enough. I guess I need some practice.fur_1800.png

The first is a view in Sketchup, second is how renders. Exploded

Yeah it's a pretty frequent issue. Only real solution is to remap the texture with a plugin like Skimp or Wrapr (I'm sure there are a few others)... Or export to Blender and redo the UV map there.

Check and make sure there isn't a material applied to the backfaces, and if there is remove it.  I think ThomThom's "Material Tools" might be able to do this.

If you don't make any progress, feel free to send it to support@cadalog-inc.com; we have a Skimp license and I should be able to fix it in a few seconds.

This looks really great by the way... the bottom composition is my favorite, although I might think twice about having brick that close to the camera without displacement. Still think it works though.
