Mti scene renders

Post by gzavye » Sun May 24, 2009 4:37 am

Just a little post to show you some images done in Maya with Mti.
And thanks to CTZn for their good advises during the process :mrgreen:

First, a comparison between a Indigo Render and a Mental ray one

1h45 with Indigo

Second a HDR test

Hi gzavye, thanks a lot for posting !

I already gave you my thoughts on the first two images, and the third, beside being really nice is welcome since I'm myself not fancy using envmaps.

See you Gzavye !

Badged Maya users should receive a link to the latest MtI beta any soon, by PM; and hopefully deep improvements are closing by.

New images done with MtI and Indigo 1.1.18
Actually I tought about buy Indigo for professionnal works; but problem is that MtI is not finished ans the development seems not to run very fast :cry:
Can I expect an up to date exporter before all "for life" licenses left?

Really nice images there :)

That really depends on Glare being able to reach an agreement with myself and CTZn to become official developers for MtI.

We have talked a fair bit about this situation, but the ball currently is in Glare's court to finish the deal.

Very nice work!
Especially like the "Black dalia" one. Simply beautiful.
Please give this guy an up-to-date exporter!!

Palette Preview

In the video I am stating that what you see is not to be released; I did not mean that. Initial release is planned to come with the agreement, but MtI is wip atm. Depending on Doug's analysis, he would continue the project and I would document and support it, or he will be writing one new exporter from scratch and I will support MtI meanwhile, before it is dropped for the new one. I'll then support and document the new exporter.

Random sounds and bad articulation for an audio track, wip mess and all: please forgive that, I thought I had to show something :D

Tell what, yes/no etc

OK for me
The palette is a good concept, and the way you do thing looks good
I like the all in one menu
But it's the front part
After that it's better with functions plugged, of course :wink:
I'm in, as always
And waiting... :mrgreen:

Most of the functions are working, the controls are effectively seeked by the export routine, but the articulation with the core is on the works.

The palette manages extra attributes, for instance it will remove extra attributes (defining the texture output) from a shading utility if this one is not connected to a material parameter anymore.

I didn't show textures I think, and error management. Errors come with a nice text and eventually propose some interaction to respond with, like the ability to point to the faulty node in a shading network. I extended the later support to include utility nodes, any valid shading network is baked and rendered, à la manière de Maya Software ;)

When this all will be stabilized and optimized I will release and focus on bugfixing, along with bridging the gap of missing features. From there adding new functionalities will be easy, the palette adds and displays them, and the export routine reads them. One expected result, is that one will not need a marine training anymore to use MtI. And another is a much lighter documentation hehe...

While this is increasing accessibility, it involves changes in the core that are not finished.

I'm doing this exclusively under the mighty will of gzavye, whose support is constant through months, thank you ! A few weeks ago you told me that you tried blendigo and that MtI had a long road ahead, I "took the fly" and revived that Palette project :twisted:

I am sorry though, but I don't want to release something now for the sake of showing how it's like, it needs more work. Hopefully things will happen synchronized.

Host/devs comments apreciated.

Here's what I came to for a material editor, export is supporting that all.

</material>
Spectrum nodes are usefull to define non RGB spectrums, tabulated data being not implemented yet. Atm spectrum nodes are returning a black color in viewports, I'd use a RGB output. Maybe the spectrum to rgb convertsion tools are in indigo utils ? Don't get me wrong, I'm not saying that RGB spectrums are not available anymore, they are just not used in that example.

No public release but I need testers for MtI, let me know if you are interested.

Comments and critics welcome on the UI :)
