I have a ShaderData plugin that I need to set value to its preview.
I know I Have to use InitRender and FreeRender to setup and destroy my data.
The problem is that Output method feels a little bit slow since I have to set the value for each UV separately. Also, I use an external lib to calculate the shader that can be done in the InitRender.
Can I avoid Output and simply set the shader preview by copying the base bitmap ? Is there any message to which I have to respond to achieve that ?
Thank you very much for your time.

no, this is not possible. You can of course create the bitmap in InitRender() and then only sample (basically copy pixels) the bitmap in Output().
