[fixed] On OSX,Wings3d 2.0.2,AutoUV Marble Shader doesn't work.

[tkbd]

I tried the newly added shader this time.
On OSX,Wings3d 2.0.2, AutoUV Create Texture Marble Shader doesn't work.
Both of custom color and a default color will not be drawn.

Here is Wings3D console log at that time.!!

Using GPU shaders.

Thanks for test it and the log. I should fix it soon.

It's a GLSL error message. It seems that some versions/drivers brand are tolerant to bad syntax in the code. I got some when porting it from a PC with Intel to my PC with AMD Radi on, but even in my PC I couldn't get this error.
So, just for information, which video card are you using and what is the OpenGL/GLSL version?

[micheus]

I evaluate better the error and all the messages were caused by the first one. So it seems to be a compatibility issue.

ERROR: 0:188: Invalid call of undeclared identifier 'trunc'

I replaced the trunc function by floor that I used in the other shaders which you didn't have problems.
The trunc function was included only in GLSL 1.30 (OpenGL 3.0).

Here is the marble.vs file for replacement.

[tkbd]

Thank you!
I was replaced with a new file.
Marble shader is working fine now.

Using GPU shaders.
AUV: Shader ´Marble´ ok

So, just for information, which video card are you using and what is the OpenGL/GLSL version?

In my Mac Mini (Late 2014) Graphic card is Intel Iris 1536MB
OpenGL v2.1 is used according to Wings3D's OpenGL info..

Version information
Vendor: Intel Inc.
Renderer:Intel Iris OpenGL Engine
Version :2.1 INTEL-10.12.13
Version tuple:{2,1,0}
2D-API: wxWidgets: 3.0.3.0

But It is different from the official information of Apple Site.
https://support.apple.com/en-us/HT202823

Mac Mini (Late 2014) Intel Iris Graphics : OpenGL 4.1

If it is compatible with OpenGL4.1,trunc function should work.
Hmm.....Wings detects the wrong version?
It is hard work in the same way in OpenGL a variety of environments,isn't it?
Good Luck!

I found another bug.
Error has also occurred in the *Noise* shader.

Info: Fragment:
ERROR: 0:393: '-' does not operate on 'float' and 'int'

Well the Mac handles opengl versions differently depending on its initialized.

tkbd, the noise_ext.fs if ready for download.

I think dgud is talking about what I read in this comment I found here.

[tkbd]

Still the same error came out.

ERROR: 0:393: '-' does not operate on 'float' and 'int'

So, I change your code to "d = (d - float(int(d)));" wrapping by float()

Then, Psychedelic noise (and other noise shaders) are workng!!
In OSX, it seems type of variable is strict.

Is it correct in this image result?

That's then problem of the variety of environment.
I can't test it properly and have to judge the fix by the error message only.

Thank you for test and share the fix.
