When I creat jit.gl.shader and save that shader, The text below is output on MaxConsole.

jit.gl.mesh: jit_gl_geometry_draw_buffers: GL Error: Invalid operation

I can use jit.gl.shader, if i delete geometry shader in my shader.

But, gl3 sample is working with geometry. ex Billbord example.

Hi everyone.

I started using jitter with gl3.
But, jit.gl.shader is not work .

What's happened?
Anybody knows how I do it?

Thanks.

zip up the shader and the patch and post it here and i'll take a look

This is zip and video that reproduces the situation.

At first, there is no problem, but saving the shader gives an error.

Thank you for your reply .

Ok, not sure what's going on here but I can reproduce and will investigate.

Thank you very much.
I look forward to your reply.

I'm experiencing the same issue. Any progress on this bug?

looking at this more closely I am not seeing a bug, but the patch is not properly setup (the mesh is set to draw_mode points, but the shader is expecting lines_adjacency). if there's some indication of what you are trying to achieve I might be able to advise.

Hi Rob, i'm experiencing the issue when using only gl.gridshape, not gl.mesh.

As soon as the default shader is saved the geometry disappears and I receive this message in the console:

Oh and here's the default shader in case you need it.

shader_test.jxs

that's only the default shader if @gridmode is 0 (quadgrid). if you set @gridmode 0 on your gridshape that shader should work. for the default jit.gl.gridshape (@gridmode 1 - trigrid) this is the default shader:

Ah I had no idea about the @gridmode attribute. Thanks!

Is Geometry shader not work with GL3?
