Skewed Texture Maps

Post by bubs » Fri Nov 28, 2014 10:03 pm

Surprisingly I've obviously never tried this before with Indigo, but I recently used a texture map skewed to fit a surface, using SU non-fixed pins. The texture looks absolutely fine in SU but when I render in Indigo, the material is distorted.

Is this function simply not supported, or is this a bug?

Don't use sketchup obviously, but in Blender that problem can be solved by subdividing the mesh.

That's because Indigo does not support homogeneous UVW mapping which SketchUp uses. UV mapping is not able of skewing.

Subdividing makes the effect unnoticeable with enough subdivisions

It's actually just an Indigo material I made Pibuz... I've always had issues with it tho...
However, I sent it to our glorious leader (Ono :wink: ) yesterday and he is having a look at it for me! If he gets the bugs out I'll upload it to the Mat DB

OK, I can do if it's more of a workflow thing... bear in mind tho, that without the use of emitting double sided thins in Skindigo, to make it look OK is always going to be a work-around with light sources hidden from the camera... and I know you don't like that sort of cheating :wink: :lol:
