Problem

Description:

So I am looking at Ornatrix as an efficient hair solution for use in my VRay pipeline. I have installed the demo, and it renders fine using the "Ox Hair Raytrace Fast" atmosphere effect in both the Scanline and VRay renderers. But of course I want it to natively work with VRay's GI. I watched this tutorial by Ephere http://www.youtube.com/watch?v=kFoc9vPbtrk

It makes perfect sense - however, I disable the atmosphere effect and the "VRayOrnatrixMod" seems to do nothing, the hair does not appear at all in the render anymore. This does not make any sense after reviewing the video, they add the modifier, disable the effect, and render. When I do this, the hair does not appear at all in the render.

Is this a limitation of the demo??? I have not seen any posts about this problem. Please help, I would like to evaulate Ornatrix for my pipeline but cannot without it working with VRay.

Using:

-Windows 7 Ultimate 64-Bit

-Max 2012 Product Update 12

-VRay 2.20.03

Steps to Reproduce:

- Install Demo

- Open Max

- Change Environment background color

- Create basic light to light the hair

- Create primitive

- Ornatrix > Add Hair to selection

- Ornatrix > Setup Fast Raytacer From Selection

- Switch renderer to VRay

- Add "VRayOrnatrixMod" to the object's stack.

- Disable "Ox Hair Raytrace Fast" atmosphere effect

- Render

Sounds like you might need to add the OX Render Settings Modifer below your Vray Modifer. Do you have that in the stack?

Thanks

Hello Michael,

Thank you for the response sir, hoping to get to the bottom of this. Yes, I had added that afterwards, as the video tutorial recommended to further edit the strands. In fact, I just created a fresh test scene and got the same results, here are some screenshots:

In case the above image embeds do not work:

I have no idea what's going wrong here. 

Not sure if I should post this as a seperate thread: I'm noticing Max is crashing occasionally while using the features of the demo? For example, while having that above scene open, I just clicked the Max icon in the top-left to reset the scene, and Max crashed. That rarely if ever has happened before. I'm wondering if the build I downloaded is the issue here?

Update: I reinstalled the demo and at the end of the installation I had forgotten that this window pops up: http://d.pr/i/qNZP

The first time I clicked, "This program installed correctly". This time I chose recommended settings. I am still having the same results though.

I have sent a message via their install support about the window that showed up after installation. I'm hoping to get an answer here or by e-mail for some guidance about the rendering problem.

 

Hello,

Regarding the installer that is message is OK under Windows 7. It should not have any effect on the installation itself.

I am not sure what culd be the cause for your Max crashes. If you can reproduce any of them please let me know. Also try to take out Ephere.Plugins.Autodesk.Max.Ornatrix.dlo file and see if it still happens. If it does then it could be not Ornatrix causing them.

Regarding VRay, please make sure you that have installed the correct VRay plugin. There are two versions of it- one for Ornatrix 1.8 and one for Ornatrix 2. You need the latter one. With Vray 2.x installers you should be able to choose which one to install.

Wow. That was it, different versioning. I just tested 1.8 and it works like a charm. I just need to update my VRay version to work with the latest Ornatrix version.

Thank you so much Marsel, have a good rest of the week!

Hey guys. Sorry to bring up an old thread but I am having the exact same problems as posted above. I am trying to play with the demo version but I cant seem to get the hair to render once I disable the atmosphere effect. I have both the "VRayOrnatrixMod" and "OX Render Settings" modifer's turned on but  none of the hair appears in the render.

Reading this thread it appears you guys solved this by either switching to the correct vray plugin for the corresponding version of Ornatrix? Sorry but I don't quite understand this. I have vray adv 2.20.02 installed and I've tried to use all versions of Ornatrix that are up on the download page.  ( 2.2.3.0 to 2.2.8.0)


Where can I find Ornatrix 1.8? Is this the version I should be using? Or should I be using a different version of vray?
 
many thanks! 

Hi Mikezoo. Yeah it seem that 1.8 has been removed from the Downloads page, so you'll need to update V-Ray to version 2.4. ChaosGroup provides free updates last I checked. Good luck.
