I can create VEX OPs to define my shaders and then Create a SOP from it and assign to my object but The shaders are rendertime.
Isn't there a way of assigning some atributes to the sceneview like colour or brigthness? I know basic materials can do it and it's related with the OGL tab but I can't define it in my own VEX SOPs?

I know it's basic but I can't find the way

thanks

After creating your SHOP click the “gear” beside it's name.
Choose Rendering Parameters and add the “SHOP options” OGL Folder.
