Max Texture size of Graphics card not obtained

March 12, 2013 | 3:57 pm

Hi,
I’m sorry if this came up already. I am having an issue with Texture sizes.
When I load a simple obj (a plane with 25 vertices and a texture assigned in the shader) in the patch of jitter tutorial #36, the texture size seems to be limited to below the specification supported by my graphics card (see below).
If I am using a texture size below 4096, i.e. from 4095 (!) the texture shows up fine, but if I am using bigger sizes, I am getting strange facetting in rainbow colors. No warning or error is printed in the output window.
Neither the actual file size nor the format seem to change anything.
Am I missing something obvious?
Thanks a lot for your help!
Marcel

hi lulasmaster.
thanks for the report.
it looks like there’s some issues with large textures under windows.

we’ve registered this as a bug, and will take a look.

hello.
this should be fixed in the 6.1.3 update.
please give that a try, and let us know if there’s still problems.
