Octane is freeze for some seconds if texture mix slider is moving to 1. It works fine until we not move it to 1.
It is caused by Invert node between texture and specular input.
EDIT : Something is really bad with this build because connecting new texture or OSL nodes to Material Inputs and disabling/enabling texture nodes if there is other node between them like mix, multiply etc. takes many seconds too !
EDIT2 :
this is caused by the new NVIDIA studio driver 516.59. Returning to 512.96 at everything works fine. It seems that Octane Core needs to be updated or driver is buggy. There is big CPU lag while reconecting texture/OSL nodes.

Is there chance to add "external" in OSL Projection node like it is in regular OSL Texture node ? Since custom OSL directiories doesn't work.
