Historically Radeon cards and Houdini have never got on. I'm not sure what the latest is though, but I believe people are having some joy. Search here (or odforce) for Catalyst - I'm sure there's a remedy somewhere for this??
benandaim I rendered a .tif file, opened it in photoshop and everything looks fine. The firewall isn't blocking mplay. I wonder what the hell is going on!
By default, Houdini will render to 16-bit floating point images.
It could be that your graphics drivers have issues displaying 16-bit float images natively.
You can do one of two things:
1) In an output driver, change the quantization to 8 bit integer (or 32 bit float) 2) In mplay, the preferences I think, there are options for Video Card preferences. In there, choose “Maximum compatibility” (or something like that). Just make sure the “Always display images as 8-bit integer” is turned on.
I don't have access to Houdini at the moment, so the wording of the options might be different.
benandaim I installed apprentice on my laptop and WA-LA no issues rendering. Maybe it's simply the ATI card it doesn't like on my desktop.
Is it just me or is the H renderer fairly slow, I've heard that C4D has a fast renderer & that's what i'm used to.
Don't judge any renderer on grid & ball scene base. Mantra is not very responsive if you compare it with freelance tools like Modo or C4D. Yet it's externally robust and powerful once you face a real challenge.
Mantra simply wasn't designed to make you feel it's fast. It's flexible and really fast in times other tools leave you in trouble.
