GLSL Shader Dev IDE needed
I want to be able to tweek shaders (esp glow and normal maps) wrapped over 3D models for Oolite 1.73+
This seems to be a familiar snag ... Here is as far as I've got - still soldiering. I have Wings3D - which is working great for creating models and uv maps. Diffuse textures can be tweaked in all their glory. I can assign bump and normal maps to channels in the engine but the renderer will not handle them. I have the normalize plugin for the GIMP - so I can make normal maps from height-maps successfully. I have Blender - which I hear can handle realtime shaders(?) But have been unable to import any of the mesh formats that Wings3D can create. It says the filetype is not recognized - obviously I'm missing something. I have the Typhoon Labs shader designer IDE - with the same problem: does not support the mesh formats that wings3D can export. I got a bit excited when I found out that the normalize plugin has a 3D preview box and a choice of meshes ... sadly, no idea how to get a new mesh in there. (They look like the typhoon labs meshes.) Right now I'm creating glow and normal maps blind. I want to be able to preview the effects without having to load the models in the game. |
what version of blender are you using? As of Blender 2.41 you should be able to import .wings files.

2.45 - and there is no ".wings" option off the import menu.
I have: 3D Studio, AC3D, AutoDesk DXF, COLLADA, DEC Object File Format, DirectX, Lightwave, MD2, Motion Capture, OpenFlight, Paths, Engineer, RAW Faces, Stanford PLO and Wavefront. Googling I see that 2.32 was supposed to be able to do that. Curious - are you supposed to do anything non-obvious? [update]I have managed to get obj files imported to blender, with the diffuse map even. I'm trying to figure out how to add a normal map to the model. If I get wings to export a format (eg "wings") which stores this stuff - perhaps blender will add it automatically? Advice - or direction to a "how to add normal aps to a model in blender" would be most welcome. |
You might should post this on a blender forum. You'll probably get better help.

At least for blender ... however, some folk here may be able to answer the central question - how to get glsl previews in linux off existing mesh + shaders.
That's all I want and blender looks like overkill. Getting a custom mesh into the GIMP normal-map 3D preview would be ideal. I've sent that as a feature request, but if I could find where the current meshes are stored, I may be able to just add a new one to the same directory... (longshot I know - with my luck, the meshes are in a binary, found the plugin in the gimp plugins directory... no meshes.) |
On the blender forums - start by wading through the simple questions sticky:

Doesn't seem to help add a normal map. I'll have to ask. |
There has been no serious progress to date - I've been using a game engine (oolite) to render models.
