Windows 7 (64 bit) + AMD Radeon HD 6570 = Can't see mesh ??

Unity Engine
1

We are testing our unity desktop app and we are having some problems with some of our new PCs running
Windows 7 (64 bit) with AMD Radeon HD 6570 1GB card

  • All the meshes (solid colour, diffuse or diffuse/transparent shader) do not show up on screen
  • But the mesh with texture seems fine, same as the graphics we draw using “GL” calls, or those rendered using GUITexture…etc .

Those PCs has the latest drivers installed already.

We found the same problem when we test the app on another PC with a older Radeon card (forgot the model number) as well.

But everything works perfectly on all other PCs with NVidia card.

So is this a Radeon card issue? And how can we fix it?
Thanks a lot for your help

do you guys think it is a common issue with Radeon cards?

or you think it’s more like something wrong/special with our computers?

or anyone running similar display card on windows 7 can tell me if you have any problems at all? (trying to figure out if the display card is supported or not )

okay, looks like we found the problem!

all the meshes created using:

meshfilter.mesh.CombineMeshes(…)

is not visible on those machines with Radeon cards.

if we don’t call the CombineMeshes and just assign a normal mesh, then it works perfectly.

So looks like we can’t use that function?
