robsdesignThanks Rob. I should have been clearer; I'm merging the hair and head objects in two separate objects, so no hair and head mixing. I'm beginning to think that some redshift attributes get left behind when merging the hair. The individual hair objects render fine WITHOUT the render-polygons-as hair ticked and the merged hair object renders as expected in Mantra. I may be missing something but I think it's an un-catered for Redshift scenario.
Hi, when rendering hair using Redshift, I would avoid merging hair with a "head" because Render Polygons as Hair will usually try to render the "head" as hair. The different look you can see could be caused by this or the hair width/thickness which Houdini and Redshift treat differently. ie. Houdini = radius, Redshift = width/diameter (or visa versa, I can't remember). This is what Match Houdini/Mantra Hair Thickness is for.

"merged_hair" renders fine for me if I enable "Render Polygons as Hair" in its Redshift OBJ properties. My guess is that Redshift treats Hair Generate nodes differently, and for the rest we need to tick that parameter.
Thanks pabcou. As you can see from my original post I mention getting the hair to render by ticking "Render Polygons as Hair" but as you can see from the included image it's very different in look from the the contributing single hair objects.

Interestingly the simple scene above works as expected in Mantra. So it looks like some sort of Redshift issue, or at the least the operation of redshift issue.

It might be a problem for Houdini in shifting to a new renderer.
You will have to wait until new version of Houdini is released.
Hi ifree
Thanks for responding. If it's a mismatch between Houdini and redshift should the original individual hair objects also not display the same non-rendering problem?

one potential cause ould be if your object is scaled on object level and you are object merging with Into This Object option
which will apply the transform to the geometry to compensate for that
however this would not be reflected in @pscele or @width attribute
so you will have to scale those yourself by the same factor
Hi Tomas
Thanks for responding. I made a very simple scene to test my problem and it doesn't look to be a transformation issue (see attached scene). I'm beginning to suspect that hair_generate objects are not meant to be merged. I wonder if anyone has actually done this? Is using the object merge node the wrong process?

Hello
I have several characters with hair, rendering in Redshift. Everything is hunky dory. For certain reasons I want to obj_merge the characters. The polymeshes, obj_merged, work as expected but the hair_generate objects, obj_merged, don't render. I tick some likely looking tickbox on the merged hair object(see below) and the hair now renders but not as expected. (I tried variations of hair width and ticking the use Houdini hair thickness box but to no good end)
Should I expect this to work? Am I merging hair using the correct method?
I'd be grateful for any pointers in the right direction

I saw your old post from 2016 about this. I've just turned off Malwarebytes and it looks like that might be the culprit. Did you ever figure out a way of them living happily together or is it a case of whenever you need to use Houdini you just turn malwarebytes off?

It mean any interaction with the software: camera manipulation, menu selection, node selection, tab key, you name it.

Hello
I am using Apprentice at home and the interface freezes every couple of minutes for a couple of seconds. This pattern continues indefinitely. Anyone had this and know a solution? I recently upgraded my card thinking this was the problem (previously a georce 760 or something like that)
Windows 8.1 64bit
1070 ti graphics with latest drivers
Thanks

Hi Dylan
I am also experiencing this. It has recently started at home on my apprentice license. At work its fine. Like you I updated graphics drivers but to no avail. Not yet discovered what is causing this.

Thanks for all your info. We'll put it in our pipe and smoke it and see what occurs. There are some positive encouraging noises for sure , we'll just need to get our hands on it and see.

Considering our options
Elegant and easy to use animation and rigging tools is one consideration for us. Can anyone allay my fears that these tools are not part of Houdini's arsenal?
