SketchUp replacing materials itself

SketchUp

Please help! I stumble across really annoying issue. Sketch up is changing materials itself, usually it’s applying one material to the rest that has the same shade (same RGB values). So let’s say I have white table top, white light bulb, and white locker in my model, and all of a sudden, when I’m about to render I’m noticing it’s all changed to the light material for example. It’s not happening every time, it’s on and off, and I cant really find a pattern. My work colleagues who are using same model don’t have that problem, so they’re blaming the plug ins/ extensions I’ve got installed. The topics on the forum suggesting it might have something to do with the copying and pasting items tho the group, but why is it happening just to me? here’s the list of the extensions I’ve got installed: 1001 bit tools, Architextures, Artisan2, CleanUp3, Edge Tools2, Eneroth Deep Make Unique, Eneroth Flatten to Plane, FaceUp, Make Unique Plus, Material Replacer, Material Resizer, Paint Both Sides, QuadFace Tools, Selection Memory, Selection Toys, Simplify Contours Tool, sketchPlus, SketchUV, Soap Skin & Bubble, Solid Inspector2, SUbD, TT_Lib2, Vertex Tools2. Please help. Kind regards, Ania

Well yes, different materials have to be different.

Id you have 2 materials with the exact same shade, it might be seen as the same material when going to the rendering program.

So if you need 3 whites, one glossy, one matte a d the last one as a source of light, better to have 3 slightly different shades of light grey.

Thanks for you reply. the real question is why is it only happening to me? Not to anyone else who’s opening same model.

Have you considered the shadows setting on your design machine may be set differently than your colleagues? It could be you have use sun for shading checked and they do not:

Thanks for your input, it was Clean Up extension, merging identical materials in the whole model.

oh yeah, while sketchup allows you to have duplicate identical materials (especially colours), cleanup will merge them. true.

I’m pretty sure that’s why in the end, I simply have slightly different materials, just add 1 to any of the RGB value, and you’re cleanup-proof :slight_smile:
