Re: Slow render times help

The only thing I see that may be an issue, is the white color you’re using. Pure white can slow things down quite a bit. If it’s an off-white color, then I don’t really see anything in the image that seems too complex.

Re: Slow render times help

i checked the override material box and it rendered in seconds. does that mean my problem is with my textures?

Re: Slow render times help

Do you have transparency on the material? The transparency slow down the render drastically.

or displacement on the water…

Re: Slow render times help

the water is transparent also the fabric is slightly transparent, i havent used any displacement

Re: Slow render times help

that doesn’t answer my question about white materials. If you’re using 100% white for any of your materials, your render is going to be slower than a snail crawling uphill backwards in a snow storm.

yes im using 100% white I had kno idea this would be an issue. so what do i do just edit the whit material to be a little off-white?

Re: Slow render times help

just make the color a little tiny bit darker than 100% white. You can adjust it in the SketchUp material editor, or the V-Ray material editor, either is fine.

I made the change still having the problem, any other suggestions?

Re: Slow render times help

100% color is = 255, I always use between 230 and 245.

Just as a test. Go to the transparent materials and change the transparent option to 100% black. Make a render to see if you have any difference. When I said transparent material, I’m not talking about material with refraction layer. I’m talking to material that have transparency on the diffuse layer.

I have this issue even in V-Ray for Rhino. I think is an old issue, at least in Rhino. Not sure if was an old issue in Sketchup.

Couldn’t you just use a 2 sided material?

The two sided material give you translucency and not transparency. If you add transparency to one of the two sided material sub-material, you will have the same issue.
