V-ray 4.2 for Sketchup GPU rendering does not handle transparency well. When I pace a png.texture with a logo on a surface then when rendering with CUDA the transparency surounding the image / logo gets black in the render. When I render just with CPU all goes well. Image 3 is a screenshot of Sketchup where you see in the outliner that there are 2 components. The logo-component has exactly the same shape and roundings as the gas-tank and is placed 0,5 mm away from the gas-tank surface. On the 2 render-images you see clearly the difference.
You could say, why making a fuss, but rendering with CUDA, specially when you have a powerful GPU, goes way faster. For 1 image CPU is ok, but I need to render an animation of 1200 images. Time is money.
Hi,
Try to reverse the faces(select the faces > right-click > reverse) of the text’s plane.
If this doesn’t work, please share the file so I can investigate it on my side.
If this is alright, please use the Pack Project tool(Extensions > V-Ray > Pack Project) to make an archived copy of the project and send it to us via the link below.

Hello,
Thank you for reporting this!
The issue is reported under SK-3826
It is happening because of the stochastic layer in the car paint. One workaround is to use car paint from the library without a stochastic layer.
