GLSL Shader Actor Tutorial
-
Dear All,
For any of you trying out the new GLSL Shader Actor, here's the HTML file with a tutorial. We don't have it on the site yet but just open the attached file in your browser.Best Wishes,Mark -
Didn't see any mention of timescale for 2.5 release with the glsl shader actor - any news on that for those of us not at the werkstatt ;)

Hi @Mark
Very keen to tryout the GLSL Shader actor. The option to input parameters into the live code is brilliant and a big point of difference from other renderers as far as I can see.Congratulations to the team for reaching another milestone and best wishes for the workshop intensives.cheersbonemap -
Hi Mark, where i can find the GLSL Shader actor ? Great show on the Opening Keynote !!
-
... just to let you know, there's a typo in the tutorial which might briefly confuse someone:
Navigate to the following folder:Mac OS: /Library/Application\ Support/TroikaTronix
should be:
Mac OS: /Library/Application Support/TroikaTronix
cheers,
John

Hi all !! The new version is available ? Or not yet Best, Maxi
-
I am guessing that it has only been released to the folks at the Workshop . . . though I would LOVE to be proven wrong.

Hi Mark,
I remember from the workshop, that the GLSL tutorial worked like a charm. I have been trying to repeat the example with the clouds and run into a funny issue under tutorial 2:
I can copy and paste the code. I even manage to see the new actor input in the background to hook up the texture for iChannel0... but I can not close the shader window without the editor compiling the code and complaining about the missing texture. If I cancel, the shader returns to the last working code. What do I do wrong? Best regards, Thomas

on line14 change textureLod to texture2D.
-
Hi Michel, thanks a lot. That worked. ;o). May I also ask why? Has the syntax changed or is it something I am not aware of?

@tomthebom
Where did you find the incorrect code? I am looking to update it, but can't find the reference. -
It's in the Clouds (by iq) shader code referenced in part 2 of Mark's GLSL Shader Tutorial
-
None of the image links in this tutorial are working. Maybe with your website redesign this little detail was missed?
-
To be honest I don't know. For another shader code I googled a similar error and there they said replace textureLog, or so, with texture2D.
Best Michel

Regarding the links: I just fixed the links to tex11, tex12, tex15 and tex16. ShaderToy hid these textures under names that change all the time, so I had to create these four and remove the links to the other ones.
Best Wishes,
Mark -
Thanks!

Hi folks, thanks a lot for your help! Looking forward seeing you hopefully at the werkstatt 2017!

@mark Has a new tutorial been made available anywhere yet? I am just playing with the GLSL Shader and the images are not working and neither is the link under tutorial 2. I am unfamiliar with code so am having issues troubleshooting some of the things I've not been able to find answers to in the forum. Thanks!
