VRay SP3a: Max 2010 rendering (a lot!) slower than 2009?!

[kein_plan]

hi i just read in the autodesk forum, that you should save the 2009 file in 2010 before rendering it in 2010. has someone allready tried this?

[vlado]

Serious, where are the problem, 3ds Max or V-RAY?

The problem is in 3ds Max.

I've tried a brand spanking new scene in 2010 and it rendered with 50% of the cpu.

That's better than what I get, mine tops out at 25%.

another bug realetd to the new "way of handling textures"
vrmesh causing appl error on cmd line render if the path set in asset tracker not match real path
the same for IES
MR proxies
DWG
...

all "external files" ...

i am sick of it

I've just gotten off the phone with Autodesk, they claim that the problem isn't with Max it's a Vray issue. Unfortunately I didn't want to pay the $300 for tech support that the lying cheating ba$tar%s wanted so they couldn't help me further.

I decided to try and trouble shoot the problem my self using a scene that I know doesn't work. I've determined that the slow down is being caused by the bitmaps in the scene and that disabling the bitmap paging doesn't help. There are two textures in the scene each one was quite large so I thought reducing the image size and file size would fix the problem. I brought them both down to no more than 1000 pixels wide with file sizes less than 2MB each and it made a slight difference. Next I recreated the two materials and re-applied them to the model and the rendering speed did increase. Finally I replaced them all together with a default Vray material and instantly I had 100% CPU usage. Obviously one of the programs is having problems with these maps as Vlado has said, the question is which one and when can it be fixed? If this is a Max problem how do we make them aware of it so they can fix it?

[vlado]

This is a 3ds Max issue; you will notice the same kind of reports for other render engines also. Autodesk are already aware of the issue (at least the guys at the ADN are, not sure how communication happens from then on) and it has been confirmed as a defect. Whoever you spoke with appears to be not well informed.

This problem takes to long time to be fixed, I have had version 2010 for a couple of months now and I can still not use it! Is someone working on this, it seems like no one know!

I've asked the guys from ADN; they told me the issue is being looked into.

I geuss what we all asking is if you have a link to a ADN site that confirms the problem. This way we can check that site for any news on the issue.

[devin]

I called my reseller this morning and had him file a problem report with Autodesk, if everyone who is having this problem would do the same maybe we would see some action on this. What I don't understand is why more people don't seem to be affected by this.

The ADN is a paid service; members are also under NDA for the stuff that goes on there unfortunately.

Well I hate to be the oddball, but I switched GI to IR/LC just to speed up the test (impatient I guess) and 2010 was faster.

2009: 2:13
2010: 2:08

I have practically a fresh install of 2010, and installed vray 2010 tonight from the downloads section. I'll try with Brute force and see if there is a difference. I have been using 2009 because I dislike the new 2010 interface and have 1 plugin that didn't work with 2010.

I should add that I am on win xp 32 bit, intel quad 2.6 ghz.

Edit: well, I stand seriously corrected.

2009: 23:49
2010: 35:11(!!!)

Someone remind me why I am paying for maintenance again. Worst interface compared to any previous version, broken plugins, and a 30% increase in render time out of the box with vray.

[KramSurfer]

Still on Max 9 x32 and x64 Here...

You guys are really making me want to just stay here...

[scottsch]

I think brute force is the problem. I set the sample scene GI to Light Cache/Irradiance map, highest settings on IR, default on LC, and changed the aliasing to Adaptive subdivision. The result of an image at 1200x900:

2009: 14 min 42 sec
2010: 14 min 57 sec

The difference here could be down to computer usage while rendering. The only difference is the image gamma is different between 2009 and 2010, with 2010 images being darker. Not sure how 3dsmax changed the gamma between the two versions. Changing aliasing to default Adaptive DMC lowers render time and looks like this: 2009: 6:20, 2010: 6:25.
