hi,just purchased the shader kit for use with my 3D engine, looked at demos and included/changed what I needed to in my editor, but when I come to apply a shader to a selected object I get an error,
here is a video showing this error:



the code to try and set the shader to the object is this:


object[n].ID is obviously where the objects ID is stored and object[n].im the image, I supposed this is how I called the shader stuff

the demos that come along with the shaders work fine so I have no idea why


I am using
SP_Init()
SP_SetClearColor(0,128,255)

in my init function before all of this and have replaced all sync commands

Because I can not think of a solution directly, I would suggest you to comment one command at a time, to check which one is causing the trouble.
Maybe also set the "generate softnormals" flag to zero just for testing.

You are not deleting the objects or use any custom shaders, right ?
But if the red marker indicates deleting objects you may want to call SP_Outline_RemoveObject(ObjectID) and SP_Toon_RemoveObject(ObjectID) before you call the DeleteObject(ObjectID) Command

not deleting a thing,they just get selected/deselected , if i press del when they are selected then yes, but I press X instead to apply shader to selected, it errors with everything to do with the shaders,including adding the fullscreen shaders to my project,the only thing that does work in it all under my engine is the custom skybox

So the demo projects work, but as soon as you try a shader in your own project it fails.
Should mean your device is capable to run the effects, but your project is doing something that interferes with them.
Can you recreate the error in a small demo ? maybe make a copy of your project and strip it down till you don't get the error anymore.

looks like that is all I can do,its really odd, I can do operations on selected objects like change all selected objects texture... so I know the texturing on my part is fine

dumb question: have you put a copy of the shaders in your media folder? And the other folder is in your projects root? and you have the sync command exchanged by SP_Sync() at the end of your loop?

I came across a really odd shader issue......left a varying in the fragment shader that isn't used anymore, no longer in the vs shader. On my desktop no bother, seemed to be ignored. On my laptop, failed to compile shader every time.

So what kind of hardware are you running on?

ah never mind..I had forgotten to put the shaders dir into the projects media folder, got some success, the glass works, but if i try the wireframe or outline then makes all my objects vanish... here is the glass effect working:





will have to try em all and see whats works and what doesn't, and why...

Just a quick tip: it seems that you are not updating the environment map after you build the level.
You may want to call SP_Environment_Render(EnvironmentID) once after you finished building the level so the map catches the whole "environment".
I say this because the the glass is very green, this could also be caused by a wrong eta value passed to the shader, but I guess you are not playing with it yet.
