Just wondering, does anyone know if it is possible to do texture translation like in tut 10 in engine rather than in lua?

problem to assign a new texture to my object
djjd Sun Jun 28, 2009 11:00 pm
Hi, All,
I am also trying to change the texture of one object I have loaded. In blender, I have assigned one material with one image. After loaded, I want to change the material with another image.
I have tried the following code, following the example in Tutorial 14:
The result is that my object is becoming transparent and show the background color. The new material is not assigned properly. But if I remove the last line of code and add the "diffuse change code" now commented, I can change the color of the object. So it seems that I have
missed something in blender object texture setting or the last line of code is not correct. Can anybody help? Many thanks!
Best Regards,
djjd
