Vray-Sketchup issue - whitening and grass texture not show

[tianyijiang]

Hello, guys,

 

I use Vray for Sketchup

 

I have found two very annoying issues:

 

1. I added infinite plane on my model, but the rendered output comes out like this: with a lot of whitened areas(see the 2nd image)

2.I used the grass texture embedded in v-ray material library, it shows in sketchup like normal grass texture, but when I rendered it, it comes out like a piece of green linen cloth(I use the default setting, not sure if it is the issue).(see the 1st image and the 3rd image)

 

I also attached images at the end of the post to show what I talked about.

 

Much appreciate if you could provide any advice!

First one looks like Z fighting. Move the infinite plane down 100mm, see if that fixes it.

 

Second issue is could be a few things. I would check the texture dimensions firstly, but ideally you would want to use something like Skatter to place 3d grass on the surface
