I have a channel shader and I want to use the Gradient Customgui but whenever I try to use it it crashes.
I am allocating it in my Init() function. Then initialize the renderer in InitRender and free it in FreeRender. That works fine in my output function.
But if I try to CalcGradientPixel in my message function it crashes. I tried allocating a second instance in the message function but that doesn´t work either somehow.
Is it possible?
Thanks in advance

I cannot confirm this. If you allocate an independent second instance in the Message() function and it crashes then it would crash everywhere. (Otherwise something is really broken.) But this code didn't crash in a menu plugin:
grad->CalcGradientPixel(0.0); // No knots
knot.col = 0.0;
knot.pos = 1.0;
grad->CalcGradientPixel(0.5); // Two knots
So what does your gradient allocation look like?

thx first. I found the problem. If I would have done it like you did that would have worked but I needed the values of the first gradient instance and everytime I accessed it, it crashed.
my pointer to the first gradient was set to NULL in FreeRender(). So now it works just fine:)
