When I apply the grass material to a Revit model, anomalies occur starting with the second surface, where another material is also applied to the grass. The material is applied outside of the surface on the other surfaces. This happens after applying the grass material to two different materials. Removing one of the grass applications corrects the problem.
The same thing always happens when applying the grass material to more than one material in the original model; the materials start failing to apply correctly to the surface.
If only one material is used, the problem disappears and the material is applied correctly. It doesn’t matter what order the material was applied or if it was changed to a different material. If it remains on only one surface, the problem disappears.
I don’t think i have replicated the issue. Is there something I have missed on the material assignment in Revit? Or perhaps you can send me the Revit Model that you have used for this one.
Hi Clov, I’m going to try it on a different computer and then I’ll let you know what happens. I’m using Revit 2026. I’m also using the same version of D5 Render, 2.11.1.0620, and the same version of the plugin, 0.4.8.0006.
It would be ideal if you could also test this behavior in lower versions of Revit in addition to the version you are currently using.
Alternatively, if possible, please share the test file you created with us. Saving the file in the Revit 2024 version would be preferable.
Sharing your test file will give us a consistent model setup for our internal testing, ensuring our results align precisely with the environment and configuration you are experiencing.
