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.

Hi,

Neither the actual file size nor the format seem to change anything.
Am I missing something obvious?
Thanks a lot for your help!

it looks like there's some issues with large textures under windows.

hi lulasmaster.
thanks for the report.

this should be fixed in the 6.1.3 update.

please give that a try, and let us know if there's still problems.
