View Full Version : Messiah 3--render problem

Hi all,

I finally got a hold of Messiah 3. I loaded up a scene that was constructed from 2.5b workstation in Messiah 3 and the render time takes way too long. The test render was at a res size of 360 x 240.

I opened up the scene again in 2.5B, rendered at a res size of 640 x 480 and it beat Messiah 3 render time even being at a larger size.

How do I fix this, I know its not entirely the program?

My computer rig:

64 bit Athlon duo core AMD processor
32 bit OS
--dont remember the graphics card but its descent GeForce

Render settings

Anti Alias = Adaptive SS, level 2, threshold 0.015, AA Pattern:Hammersley,size 1.5
Depth of field--none
Lightsource:all, GI type:Monte Carlo, GI samples:3, GI Depth:1 @ auto reduction,GI Intensity:1.0

All render settings are same in both older 2.5b version and Messiah 3.

Anyone have a clue on whats going on?

Thanks,

Cypher

I guess it is hard to say at this point. A lot of things has changed as far as rendering goes. It may be the way shaders are layed out in your materials. You may need to recreate some of them.

I will setup the shaders again and see what happens. I will record what I am doing too for reference and tutorial archives.

Thanks for the input.

Any other inputs are more than welcome.

Hmm, try with the GI noise reduction on, that's the new GI mode in 3 and pretty much renders the other modes obsololete in most cases. It's smoother, and quicker than any of the other modes.

That's an odd one as the GI in general in v3 is quicker / better quality than 2.5b / 2.5c, even without noise reduction on.

Any chance you could post a screen of the render in both version ?

edit - have you checked you're using both cores in v3 ? Check threads is at 2 in the output tab, and set chunk to 'files' - set at 16 - or 'Y res'. The latter is normally a bit quicker.

Messiah3-5minute Render (http://www.mediafire.com/imageview.php?quickkey=mmmwqzdjtmi&thumb=4) - v3/16 chunk, 2 thread, 320x240 = 5minute render

Messiah3-4minute Render (http://www.mediafire.com/imageview.php?quickkey=oenlxbxxtzo&thumb=4) - v3/Yres, 2 thread, 320x240 = 4 minute render

Messiah 2.5 - 19Seconds (http://www.mediafire.com/imageview.php?quickkey=ozwtynl5oub&thumb=4) - v2.5b/ 8 chunk, 2thread, 640x480 = 19 second render

Tried the GI reduction and it still took minutes for the render in Messiah 3. It was a touch faster. Also, it changed the way my texture looked on the procedural sphere.

GI Reduction Messiah 3 (http://www.mediafire.com/imageview.php?quickkey=jjqnjej1rlp&thumb=4) - v3/Yres, 2 thread, GI noise reduction on, and @ 640x480. This one was a little under 3 minutes to render one frame and this is what I was talking about the texture being differently rendered. Texture bleeds when GI reduction is on.

Don't know what is going on here with the render times. I think it has to do with the shaders because I rendered another scene made from 2.5b, loaded it in Messiah 3, no shaders (only nodes was covering multiple displacement maps) and the render times were similiar. Messiah 3 was a touch faster but not much.

I was using dolleye shader with textures on a procedural sphere.

Any other ideas would be great.

Thanks!

Cypher, would you be able to post the scene ? Or try the shaders on a 'proper' sphere rather than a procedural one.

I tested the DollsEyes examples that come with Studio in 2.5c / v3 and they didn't show the excessive render times you're experiencing, which points to something in your scene causing the issue.

From what I have heard the renderer in V.3 for MontiCarlo GI is basically a hybrid Monti\Photon Map solution. The new settings in the Noise reduction are what is important to address.

I am still working out the settings, (and they are specific to each scene as well.)
The settings determine the "Treshold" at which point the photon renderer will switch to Monticarlo.. so that is why you can see such a difference when changing the settings.. There seems to be a sweet spot, where if you can get it right the photon calculation will kick in and make the render faster....like you saw in v.2.5..(except that in V.3 there is Much less noise).. If you change settings that force the Monticarlo calculation.. you are in for a slow ride :)

We definitely need a thorough explanation on this..but I think we will need to wait for the dev\doc team to have time to give us the low down.. Until then, try mucking with the Reduction settings and use higher photon counts.. (i think :) )

Just posting on this thread to keep it alive. Havent had time to redo shaders and properly figure out what is wrong with the render time in Messiah 3. -Been modeling for current projects.

Whatever it is, it is definitely irregular.

I have tried everyone's comments and suggestions and nothing works. I will have to rebuild the scene again in Messiah 3 to ulitmately figure out what is going on.


Thanks to all and I will post again with results.
