View Full Version : texture disappearing on pickup?

ooookkkk, this has to be the weirdest thing i've seen...

i'm implementing a routine to pick up objects and hold them. so far so good, minus one tiny problem; if you pick up objects which have a texture, they look kinda...funny...check out these pix:

no texture:

held: http://virtual.ne.uiuc.edu/nick/debug20030929/notextureheld.jpg

with texture:

any ideas what's causing this?

A bug in your OpenGL state management, most likely.

Blending is being enabled when the chair is picked.

I expect you have it attached at a different place in your code when picked and the effect is blend state, blendfunction and/or alpha is therefore different when you enter the code to draw the model.
