I have possibly not so a common a task done from Houdini FX and Mantra, I create various VFX via Pyro or Particle System inside Houdini and need to render IMAGE Frame in PNG format with Alpha Channel. I admit im not a grand master however I'm hoping someone in this forum has successfully done this.
The issue is color, when i render PNG (RGBA_Alpha) SRGB, the image generates some black color that does not exist, and a very muted version of original view seen in mantra.
I have provided a before and after image to help explain what is happening better, Below is frame 70, this issue seems specific to PNG only or more specifically when alpha channel is applied, without alpha channel i will get good result.
If I render EXR and or TGA, bring into to composting software like NUKE or After Effects, same issue when converted to PNG.
in the example below i added a black ground in bottom image to show how muted the image becomes, Im wondering... does anything special need to be done to Houdini channel before rendering to a PNG?
thanks in advance,
