Speedtree to 3DsMax Not Respecting Material ID's

I am exporting from Speedtree 10 to Max for Corona. Using the Speedtree importer for Corona inside of Max I am getting some odd results.

When the geometry comes in it is all assigned the same material. The Multi/Sub-Object Material is created properly (as you can see in the screenshot) but it is not applying them correctly. It appears that it is giving all objects the same material ID number of 1 and therefore assigning everything the first material in the stack.

Has anyone had this issue?

Thanks!

Hi @RB_VIZ,

Our devs are going to need to take a closer look at this one. I’ve logged it, and we will post here if we have any updates.

In the meantime, you could potentially try using .usd!
