Indigo Renderer Forum

Hoping someone can help.

If I create a completely sealed box in Sketchup and then render it (nothing else - just a box) with the camera inside the box, I get light leaks at all the joints.

The geometry says this shouldn't be possible.

I am using Sketchup Pro 2019
Skindigo 4.2.21.3
Indigo RT v4.0.66, OS X 64-bit build

Why is this happening? Also, is there a newer version of RT? I can't find a download for it.

THANKS!

Hey Paul.
This kind of problems are usually modelling related.
Please make sure everithing is ok with your scene.

Hi Originalplan

I know what you mean wrt geometry. However, all i have done is create a square and then used push/pull to create a cube. At this point the geometry is as solid as you can get.

The render you see is by placing the camera inside that box with sunlight as the environment outside.

If i render it, i then get the light leaks.

This, I guess, suggests the problem is in the generation of the export from Sketchup to Indigo as the edges are definitely co-incident in the Sketchup model.

Any ideas?

Thanks for your help!

out of my head
a) use cpu
b) put a light inside the box
c) don't chose reinhard
d) model the the walls so they have weight

Pixie is right. It’s a precision problem with GPU rendering that can be worked around with above mentioned methods.

Thank you guys - I will give those a try and see how it goes!
