Hi everyone,
I need some help with visualizing an OSL shader in Verge3D. The shader works perfectly in Blender, but I can’t seem to get it to work in Verge3D. Here is the code I’m using:
float pingPong(float x, float period) { float twicePeriod = period * 2.0; float modX = mod(x, twicePeriod); return period - abs(modX - period); } float frac(float x) { return x - floor(x); } point hadamardFraction(point v) { return point(frac(v[0]), frac(v[1]), frac(v[2])); } shader tejido( point Vector = P, int CantidadFilas = 60, int CantidadColumnas = 46, color Color1 = color(1, 0, 0), color Color2 = color(0, 1, 0), color Color3 = color(0, 0, 1), output color Col = 0, output point VectorOut = 0 ) { float columna = Vector[0] * CantidadColumnas; float fila = Vector[1] * CantidadFilas; float pingPongCol = pingPong(columna, 1.0); fila += pingPongCol; VectorOut = hadamardFraction(point(columna, fila, 0)); VectorOut -= point(0.5, 0.5, 0.5); }
This is the shader in blender:
And the node setup
Any suggestions or advice would be greatly appreciated!

Puzzles and JS coding. Fast and expensive.
If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.
2024-06-03 at 1:19 am #74500Ignacio DíazCustomerI’m attempting to visualize a procedural texture created with an OSL script in Verge3D, but it’s invisible. At one point, I was able to preview it. I’m currently not using puzzles; instead, I’m using the app manager or sneak peek to check if it’s working. According to the Verge3D documentation, OSL shaders are supposed to be compatible with Verge3D… I hope there is a fix to this.

Thanks for the scene, it helped a lot!It appears that the OSL node inputs are not corresponding to the inputs in the shader itself. Maybe it’s a bug or a feature of Blender, but it causes crash in Verge3D. You can easily fix this by creating a new node with the same shader code so Blender assigns inputs in correct order:

2024-06-07 at 2:40 am #74597Ignacio DíazCustomerI first tried creating the same procedural texture using shader nodes, but it didn’t work well in Verge3D. Is OSL fully supported by Verge3D?

Glad it helped! Most OSL shaders should work just fine, however we only support procedural textures, e.g. it’s not possible to compose a complex BSDF shader.
2024-07-28 at 4:05 am #76224Ignacio DíazCustomerHello again,
I’m having trouble getting the new version of my OSL shader to work. I followed the same procedure to create a new script node, but it didn’t work as expected this time either. Any suggestions on what might be going wrong?
Thanks in advance!
PS: Is it possible to use GLSL scripts with Verge3D? Because there aren’t many learning resources available for OSL.
