#9 Texture sampling differs from shadertoy's

[Victor Beaupuy]

Hello !

I'm trying to run shadertoy's projects with synthclipse, and noticed the textures are not exactly like shadertoy, once sampled by the shader.
Making glitches when using 3D noise function from 2D noise texture. Like in some of the example : volcanic (iq) : https://www.shadertoy.com/view/XsX3RB

I suppose this is because of the sRGB, and compression options. Is there a way to disable those parameters ?

The Volcanic shader worked fine before. It is even an official example available from the Synthclipse main menu.
I checked some older versions of Synthclipse and in 2.1.1 the Volcanic shader renders correctly but in 2.2.0 not. So clearly you found a bug introduced in the newest version.
Thanks for the report, I'll try to fix it tomorrow.

Awesome !
Many thanks !

This should be fixed by now. Please check the newest version:

Indeed, my project behave exactly like in shader toy !
And about the examples they do as well, except some shaders that has been modified since you imported them in the release :

-volcanic (camera motion blur w/ buffer)
-woods (slight change of colors and hash function)
-rounded voxels (camera angle and hash function)
-fractal cartoon (vignetting color)
-Space Race Lite (link to shadertoy dead, new version : https://www.shadertoy.com/view/XtfGzj)

This is only slight changes, so not that much important.
And once re-imported from shader toy through the UI, they work fine.

Thank you a lot for the really fast fix !
