Bright grass

Hello, i am architecture student and i am working on some visualization for a project.
In my scene i want to use colored (non green gras) but as you might see the gras reflects on my structure which i don´t want to happen. Is there a way to prevent this from happening, whithout turning of the refflecitve layers of the other materials.

Bright grass

That’s not a reflection as much as a color bleed / light bounce which is otherwise why Vray is such an excellent rendering engine.

Plan 1. To avoid this color bleed, you might try rendering two passes and compositing them in Photoshop.

Plan 2. Change the grass color to neutral grey and render. In PhotoShop, create a purple overlay layer for just the grass area.

Thanks for the tips, i changed the grass texture anyway now.

Yup, that works

Cool installations! All in all, losing the purple grass was a good move.
