Hi, do not use x^2 but instead, use x**2, in Ruby the ^ operator is a binary xor. See the operator list for Ruby...

https://www.tutorialspoint.com/ruby/ruby_operators.htm

Try this formula...

((x-y)**2)/20

oh I see what you mean. You have a face (a wall) with a texture on it and then you have another face with the transparent PNG that you want to put on the wall, making it look like it's painted on the textured wall. Then yes, Numberobis is correct, you need to offset that other face because if they both occupy the exact same space, how can Skp or Raylectron know which is priority or not? It can't. It's not a bug. Offset by just even 1mm should be good enough, OpenGL in Skp may not show you it is when you orbit but in Raylectron, it'll render properly and you won't get any shadows from it being offset.

I was looking at SU3.jpg and it's not a PNG. Someone else posted one, TuNA so I didn't bother with that one. which one is it? Better yet, can you post the PNG and what it looks like in Raylectron? along with the Raylectron settings for that material?

Make sure your PNG has a transparent background, looking at the post above, it appear not to have a transparent background. You can use Photoshop, Gimp or similar software to remove the background, save it and problem solved.

Make sure the bitmap is 24bit and that it doesn't include color space information.

I did but it doesn't work

Make sure that the fur_en folder and the fur_en.rb file is in your ..*Sketchup\Plugins* folder and re-start Sketchup if it was already opened.

if that doesn't work still, then let me ask.. what doesn't work? The fur plugin? or it's not in your Plugin menu? Give me some clues.

Thank you, I downloaded it via IE. I put this unwrapped folder 'fur_en15a' in folder 'Plugins' in SketchUp files but it doesn't work. What should I do?

You must unzip it to that folder.

rps_texturewrite.rb is not part of Raylectron, it's from Renderplus, so you may want to contact them.

The Raylectron texture exporter is very fast, and, you can select the format you want to save the images as, and where to save them, and, it's easier to use, with a nice GUI.

wow! that is weird! but thanks to let me know how you fixed it. I wouldn't have though of a reboot to fix it!

I can't make it to do that! I've tried everything, even loading another model without exiting SU, and it comes up everytime! Maybe the window has moved behind the SU window?
