strange color problem - leggo - Aug 25, 2004 03:58 PM I have a "spaceship" coloured in shades of green the problem is that when I enable lighting the colors become light blu, white and green what could it be? strange color problem - Sohta - Aug 25, 2004 04:07 PM Screenshots would be really helpfull here. Otherwise, it could be a number of things... off the top of my head: - When using lighting, materials are used instead of colors, unless you use GL_COLOR_MATERIAL. Are you setting the materials properly? - Do your "shades" of green have non-zero green and red channels? strange color problem - Jake - Aug 25, 2004 04:08 PM You really didn't tell us anything that could help us solve your problem, it could be hundreds of things. Are you sure your light is white? strange color problem - leggo - Aug 25, 2004 04:17 PM yeah my light is white and I've enabled color material... sorry for the short post but I'm a little tired I'd post a screenshot, but I don't know how to take one under osx strange color problem - Nick - Aug 25, 2004 04:27 PM Go to the applications folder and then go to utilities. There is a program called grab. Then go up to capture and choose how you want to capture the picture. I personally like just using the selection tool. Don't worry the popup is invisible in the picture so don't worry about moving it. strange color problem - leggo - Aug 25, 2004 04:29 PM tnx! tomorrow I'll post some screens... now I need to slee... strange color problem - arekkusu - Aug 25, 2004 04:40 PM You don't have to use Grab. Just press Cmd-Shift-3 to get the whole screen, or Cmd-Shift-4 to get a selection. Or Cmd-Shift-4, space to get a window (does not work with OpenGL content.) This is documented in the Mac Help, btw. strange color problem - Nick - Aug 25, 2004 04:51 PM Oh ok thanks. I didn't even know that. Wait, you said Cmd-Shift-4 twice. Which is which? strange color problem - Sohta - Aug 25, 2004 04:58 PM The second one is Cmd-Shift-4-space. strange color problem - Nick - Aug 25, 2004 05:02 PM Oh I was thrown off by the comma in there. strange color problem - leggo - Aug 26, 2004 03:30 AM without light: with light: the model is copyrighted, so please don't steal the magnificent model idea or my horde of lawyers will eat you strange color problem - leggo - Aug 26, 2004 04:33 AM maybe the solution lies here: I'm importing models from meshwork, so to find a triangle color I divide the color of the material by 65535 (the program uses a 0-65535 scale) the fact is that the colors I get with the lighting enabled are the same colors I get If I don't divide the colors by 65535 hope it helps someway strange color problem - leggo - Aug 27, 2004 08:36 AM I've resolved switching to wings3d and obj files... now the colors are ok
