Playing a movie on a model #201890 04/11/08 21:25 04/11/08 21:25

What do I need to do to get a movie to fit exactly onto the plane? EDIT: So the problem seems to be that the model's texture maintains the ratio of the original skin, even after I call ent_setskin during runtime. For instance, if the model has a 256x256 texture in MED and then I call ent_setskin with a 320x240 texture, it will apply the new texture as a perfect square rather than with the new ratio. Is there a way around this?

Try a wait(1); between setskin and mediaplay. I honestly don't think it helps, but worth a try eh $\:\)$ . Click and join the 3dgs irc community! Room: #3dgs

They require power-of-2 texture sizes (32, 64, 128, 256, 512, 1024...), like 64x128 or 128x512. All other sizes are automatically 'inflated' by the engine to the next power of 2, however at cost of video memory, performance, and image quality." cheers
