Maya DirectX11 Technology Viewport


#161

Anyway I’ve put my money where my mouth is and moved on i doubt i’ll post in this forum segment again.

We’ll try to miss you, then.

I enjoy many other tools outside of Maya, but have never felt “burned” by Autodesk and especially not by the devs, who have gone out of their way to help me every chance they can.

And the new viewport enhancements fully rock not just for game development but for my work too, arch/viz. This is not a niche, this is construction, which is the single largest industry in the entire history of humanity. If you think it’s a niche, you’re living in one right now.

:applause:Brilliant.


#163

To bad you missed the entire context of the discussion… When this thread/tech was first shown off it was marketed in such a way that it was percieved by many people and not just myself as a major update to the base viewport which would give a really high quality game like display of what your going to render.

As the discussion unfolded it became clear this was a specific feature for game developers which bummed some people out since the VP2 in 2013 by most accounts was still rather incomplete…

Since the 2014 has come out and from what I can tell VP2 uses dx11 and has been improved which is what everyone wanted to begin with…

Continue your witch hunt if it amuses you…


#164

I intended no hunting at all, but was simply disagreeing with you about VP2 being a niche upgrade. It can be very useful in many areas of work. Modo also can, and just about every other application has some use obviously in its areas of expertise. If another program can help you get your work done, then by all means, use it! There is no need to be “loyal” to a piece of software.


#165

Man, I step away for a few days and it’s WW V!! I have a relevant question…I hope…has anyone tested VP2 (old and new) performance using CAD data? I’m thinking automotive CAD. I had the unpleasant experience of constant crashes and I’m wondering if anyone else had a similar experience. I know this feature is hardware dependent, but any suggestions on how to better optimize the data to avoid these kinds of issues, or is this an unfortunate consequence of the CAD data being crap to begin with? Any thoughts are much appreciated. I can be civilized you see :slight_smile:


#166

The debate was over the DX11 viewport which was seperate from vp2 at the time, my entire gripe was why they weren’t putting resources into vp2 which more people would use instead of a feature aimed at high end game developers since the later would benefit more people…


#167

You can put your gripes to rest then because the Maya API is platform independent and so is VP 2. So any work that had to be done to support DX11 viewport directly benefits VP 2 API.

DX11 was a much requested and much appreciated features by a significant number of users.
You just don’t happen to be included in that group.
Just like many of our users never use some of the features you value the most.

You can also put to rest the illusion that OpenGL is on par with DX11 on all platforms.
Simply not true. There would be no way for you to run OpenGL 4 on a Mac for example.


#168

Oh i have and I’ve moved on :slight_smile:

But it is good to see VP2 improve…


#169

@rBrady
I love your post, specially your list. It make me realize a lot of thing. :buttrock:

I’m very interested by this. Does this mean the Viewport API will be more “modern” and platform independent (choice between DX/OpenGL)? As DX et OpenGL 4 API have almost the same functions? I just wonder about the VP2 future. i’ve read documentation (a pdf) about “how write viewport code with VP2” but didn’t really understand. It’s seems to be a way to remove direct drawing (even if Maya 2014 have an interesting new class for this).

Just my two cents on this: This is not a OpenGL problems here. Many devs are angry against Apple who never update it’s drivers, even if hardware is capable. But OpenGL “fragmentation” is one of it biggest problem, specially on Apple hardware…


#170

I second that…


#171

One thing thats been broken for a while now in VP2 is the way it handles textures. With VRayMtls, it’s applying a serious gamma correction curve to every texture making the viewport excessively dark. (For the obvious, no I’m not using any gamma correction nodes).

Hopefully can be fixed in the next update soon.


#172

Not sure if this was posted… its been out for a while…

soooo these uber shaders render perfectly in Mental ray I’m assuming because they wouldn’t (?) spend so much time on development or letting us know we could set up a shader that would have to be stripped out for rendertime. Right? hahaha Yeah,… as broken as Viewport 2.0 is, I’m sure of it. {sarcasm}


#173

I am not sure I understand your sarcasm, but I will reply anyway.

The Uber Shader is a DX11 GAME material.
So no, they do not render in Mental Ray.

It was never the goal. If it had been the goal, we would have done so.

However, Mental Ray materials can make use of the same VP 2 functionality to render real-time materials in the viewport. I think (just guessing) that would be up to Nvidia to add since it is their renderer.

Some of our game customers would have the opposite reaction to you if we had spend all this time making the Uber Shader render in Mental Ray, they would have told us to just spend more time adding features to DX11, because they do not need to render the full shader in Mental Ray.


#174

Just to answer to this: No. From what I know, anytime we complain about MR stuff on Nvidia forums, devs told us to make AD aware of our problems. They say they are just working on MR renderer, not specific 3D package integrations.

It seems that few things are changing. mayatomr seems to be a real collaboration between AD and NV now. It was not the case before.

It’s not DX11 related. I just answer about this specific point. :slight_smile:


#175

Can this shader be used in game engines such as Unity? Is the shader provided and licensed for use in a game engine?


#176

It lacks a field for a Gloss map, useful in the production of Game Asset.


#177

The shader is provided here: $(MayaInstallDir)/presets/HLSL11/examples/MayaUberShader.fx

It’s in HLSL. Unity4 has some restrictions about what it supports for DX11 specific HLSL syntax, which you can read about here:

http://docs.unity3d.com/Documentation/Manual/DirectX11.html


#178

Cool - I haven’t installed 2014 yet but this is a bit interesting. I had some issues with 2013 and plugins and that’s finally settled. It was more painful that release than any time before so my jump to 2014 will be a while. I simply don’t want to deal with that.


#179

I’d love to have a ubershader workflow to Unity. If I have some time I may try and get that to work.

It appears that Max often does some swapping and adjusting of shaders behind the scenes when you switch renderers. I think maya could do better with this. If you are using an ubershader and you switch to mr, it could setup a mr material that is visually very close to what you had in your ubershader. It’ll never be the exact same, but 3DS Max has show it can be done and it can be very useful.
