Shader Model 2 Plastic        

Shader Model 2 Plastic Shader


This shader is exported from rendermonkey 1.61 with one change to one line of code in the .material file as noted below. Can't find the rm exporter on the web? It's posted to the bottom of this page.

It should work with gpu's that support shader model 2 and above. A live Openspace scene (that uses Ogre for 3d, Newton for physics, OpenAL for sound) is posted to: You need win os or linux running wine and the scol voyager plugin (from ) to view the scene. If the plugin is not installed on your system you will be prompted for an install. Openspace like Ogre is opensource.

The upside to this shader like any of the rendermonkey shaders is that you can fool around with the variables in rendermonkey and preview them instantly in that app.

I think there is a bug in the rendermonkey exporter. With some help of one of the developers of openspace, I found that you should change the line:

param_named_auto 0 world_viewProj viewproj_matrix


param_indexed_auto 0  worldviewproj_matrix

otherwise if you transform the object that is painted with the shader, the shader won't move or scale along with the node that holds the entity on which the shader is painted.

colleagues: feel free to remove my commented out code, -h

Here is one of my monsters painted in red plastic:


Just add the material rmplastic to your object.I have not modified it to work with hardware skinnig. Anyone who wants to do that go ahead and edit this page an add the hardware skinning version below mine.
