i fully agree, You can not go back. if You have You will start missing many things. I have to. It may be not the fastest for simple scenes, but mantra is very robust and scales very well. Try to render things with motionblur depth of field and displacement. You will love houdini's mantra ( haven't tried renderman). On the otherside most other renderers are like a blackbox compared to mantra, unless You put Your c++ slippers on, that's another nice feature of mantra. easy to enhance.
dont't let the beginning troubles stop You. It get's easier day by day.

You can instance lights like any other object. just use a pointSOP and set the instance attribute to the light. On th object level You have to add the point instance render parameter and set it to true

some parts are locked. like ifd rendering and stuff like that, but for testing and learning everything is there. the biggest limitation is that You are not allowed to use it for commercial work. thats why it is called starving artist edition. but it is a real great offer

i still have a basic question about linear workflow.
for all renders, especially with global illumination, gamma 2.2 looks much more natural. at gamma 1 they do look much to dark.
now i tried to view a simple linear gradient. viewed at gamma 1 it looks better, than viewed at gamma 2.2. it just looks not evenly, I tried it in mplay and nuke( here I used sRGB). But with 2.2 gamma a linear gradient does not look correct. what do I missunderstand here?

good to know. but this does not prevent the colorpicking issue, unfortunately
does anybody have a LUT for sRGB to share?

Hi there is anotehr way of doing this. I attached a file. I use a vopsop to generate a attribute onto scattered points that I can later use in a delete sop. this is quite fast and I can use this points as source for my particles.
have a look it it works for You .

PS: Ieek, empty space in the filename !!

I thougth this should work. I want to split particles from the volume of a instance. the split node offers this option. but unfortunately it kills the inherited velocity. is there a workaround?

When you create local material parameters on a object with a displacment material You don't get the displacment scaling as scale parameter allready exists on every object. maybe the displacementscale could be named different by default

the vtms I have in mind should work quite well in 9.5 with some fixing. I guess it is easier to pick up 9.5 than 5. the helpfiles are quite well done.
Why waste time with a outdated version. what kind of computer do You have?

Hi,
When I set the mantra verbosity level to 1 on xp64 a little window pops up as soon as i start a render and shows me things like shadowmap generation and rendertimes.
on linux (ubuntu) nothing happens. How can I fix this?

If You want really instances with all their benefits and drawbacks, go to the objecct level select teh particle object and click on the little gear object at the top of the parameter pane, now select edit rendering parameters and search for the parameter “Mantra9.5>Instance>PointInstancing”, drag it to the right tree and click accept
now You got a new paramter Point Instancting at the objectlevel, turn it on and render. now You can see the donuts. by default the parameter is of so the instance information is not piped to mantra.
