HEy Oliver, thanks for your Feedback.
The Texture resolution is 2530*889 px
i know, not really a power of 2
Just added the ivy directly from GIMP to see some results in Blender, to get a better feeling for the leaf "density".
The lack of Detail in the Texture should be come from the mipmapping / bad alpha clipping in Blender itself.
If ive made some more Models for the whole environment, i would create an "ingame" scene with Normal mapping / shadows and all the fanciest shader stuff
Thanks
Sebastian
