Texture is upside down

Hi,

I must be missing something very obvious.. I can't figure out why with a default texture-to-plane setup the texture always appears upside down.

What should I change to this patch to make it work? Rotating 180 degrees around the z-axis isn't a very neat solution..

Thanks,
Mattijs

A little update: this doesn't occur when the texture is sent directly to the videoplane but only when the texture stored in render is used.

I modified the example to illustrate this:

this is due to the fact that the texture coordinates originate in the
lower left corner of a plane: cf. the geometry matrix in the jitter
manual && check out the cmdlist in the attached butterfly patch.

save as:

butterfly_02.mxb

Thanks Jasch, it'll probably require some time for me to figure out your patch but I will do so asap. It looks like this is a way to directly assign texture coordinates and that is what I need.
