Title:	VRay 3.6 can't render hair
Category:	Crash/Critical
Status:	Open
Posted By:	jsnferns ( Jason Fernandes )

Problem

Description:	Vray can't even begin rendering. Crashes immediately with Vray Exception Error above. Please note, it works if I convert strands to mesh, but that is undesirable. This problem is happening in VRay 3.6 with Max 2018. I have tested my installer as well as the same scene setup in VRay 3.4 with Max 2017 and everything works great. Also I don't have the Ornatrix toolbar showing in Max 2018 and neither are the icons showing for the modifiers.
Steps to Reproduce:	Just create hair, render in Vray 3.6 for Max 2018 not working.

Jeordanis Figuereo	Hi, What build of Ornatrix are you using? Use the following command in MaxScript listener to add Ornatrix toolbar: `-- Adds Ornatrix toolbar to 3ds Max OxAddToolbar()` Jeordanis Figuereo (Product Designer. EPHERE Inc.) LinkedIn Discord

jsnferns	Hi, I am using Ornatrix 6.0.5.14700 Ok for some reason the cuix editor.dll and authorizer.dll didn't get copied over. But now that I have copied them to the Max folder, the rendering problem still persists. Also when I try the OxAddToolbar().. it opens the script editor and highlights at : Line 708 ( OxGetCuixEditor() ).AddToolbar (OxGetMaxIntegerVersion()) (GetDir #maxData) (OxGetToolbarRemovePattern()) "[ \\t]*" toolbarText OxAddToolbar() -- Error occurred in anonymous codeblock; filename: C:\Program Files\Autodesk\3ds Max 2018\scripts\startup\OrnatrixUtils.ms; position: 28656; line: 707 -- Runtime error: .NET runtime exception: Access to the path 'C:\Users\Jason\AppData\Local\Autodesk\3dsMax\2018 - 64bit\ENU\en-US\UI\Workspaces\Workspace1.cuix' is denied. -- MAXScript callstack: -- thread data: threadID:9844 ..... -- Externals:-- Error occurred in anonymous codeblock; filename: C:\Program Files\Autodesk\3ds Max 2018\scripts\startup\OrnatrixUtils.ms; position: 28656; line: 707 -- Runtime error: .NET runtime exception: Access to the path 'C:\Users\Jason\AppData\Local\Autodesk\3dsMax\2018 - 64bit\ENU\en-US\UI\Workspaces\Workspace1.cuix' is denied. -- MAXScript callstack: -- thread data: threadID:9844 Ornatrix Warning: Main parameter map is not initialized Thanks

jsnferns	I was able to get the ornatrix toolbar back through loading DefaultUI from Customize User Interface Toolbar tab Icons are working as well. However rendering in vray still isn't working. Same error: error: UNHANDLED EXCEPTION: Preparing instances Last marker is at ./src/vrayrenderer.cpp, line 4130: Preparing camera sampler

Jeordanis Figuereo	Hi, sorry for the delay. I see you are using V6, please have in mind that this version is still in beta and is recommended for testing only. To solve the rendering issue make sure you are using RenderSettings modifier to change the thickness of the hair strands instead of ChangeWidth modifier, this one is not compatible with VRay yet (Will be soon).

jsnferns	I've been using the Render Settings Modifier not changeWidth.
