[Max] Bug Reporting / bitmaps not showing
« on: 2023-09-08, 11:06:41 »
Ive really struggled to get bitmaps to show consistantly in Max 2024 and corona 10. Some of them work but some dont, even when toggling the show bitmap button on the slate editor ribbon. I've tried different display modes like high quality but that makes no difference. Its a corona issue because if I recreate the same material with a standard max material with the same bitmap and real world scale settings it shows up fine but switching back to the corona material they disappear again. Its the same whether I use a max bitmap shader or the corona bitmap. Any ideas? Seemed better in Max 2023 and I seem to remember reeading the release notes that there were some 'improvements' to the corona bitmap display in R10 but thats not been my experience.

[Max] Bug Reporting / Bump in layered materials
« on: 2023-07-14, 13:50:58 »
Not sure if this is a long standing limitation of the layered shader as I've not noticed before. But it seems like only the bump from the base material can be used - is that right? Displacement works with the different options like blending but bump is only from the base material which seems like a strange limitation when displacement can be blended. If I remove any bump maps from the base material then the material is just flat, even with layers above that have bump switched on are active in the layer shader. (no displacement used).

General CG Discussion / Autodesk Black Friday discount terms
« on: 2022-11-02, 10:04:39 »
We signed up for three year subscriptions on a Black Friday deal coming on for three years ago now so are due to renew. At the time I couldn’t see anything in the terms about it saying for new customers only, which is usually the case. Has anyone got any experience with this as we could just potentially buy again on the deal if it comes up and not renew our existing licenses if it’s open to anyone?

[Max] Feature Requests / Auto fix for normal shading warning
« on: 2022-10-19, 11:47:09 »
I couldnt see this on a quick search of requests, so sorry if this has already been addressed or is in fact possible already. But is there a way to just tell corona to correct the normals for those flagged up objects? I know on occasion Corona thinks they are wrong but actually they are correct as is but if there was a check box we could tick for every flagged object to say fix it that would be really handy. Most of the time when there are dozens of objects flagged, unless its obvious we just ignore it but it would be good to have them fixed if we can.

Just wondering if anyone puts all their Tex maps in to a single folder and path max to that? We seem to have loads of paths and folders for various texture / model categories and wondered if this is slowing scene loading / render parsing that could be helped by throwing everything in to one folder?

[Max] Bug Reporting / IPR only using 50% CPU Corona 8
« on: 2022-04-27, 10:25:35 »
Im working on project with the final Corona 8 release and my IPR maxes out at approx 50% of my Threadripper 3070X. Full render is 100% CPU and new simple test scenes are also 100%, also sometimes a fresh restart will trigger this scene in to 100% IPR usage but it will soon drop back to 50%. Tbh it feels even slower than 50% in use. There are no overrides on threads in the system options they are the default -1. I've not had this before and only noticed it in this first scene I've used with the final v8 version. Anyone else with this?

Plenty of spare RAM and its been happening since there were only a handful of mats in the scene so its not overlaidened.

[Max] Feature Requests / Saving exposure bracketing
« on: 2022-04-15, 23:12:25 »
Would it be possible to add saving exposure bracketing like a camera as passes? Sure we have the option for light mix but it could be really useful to set a standard image as we do currently then an over and under exposed image with a tone mapping setting for each to avoid too much blow out. I know we can always save in corona format and adjust with the standalone or save as 32 bit but both those options have their drawbacks.

[Max] I need help! / Slow UHD Cache
« on: 2021-07-29, 14:50:38 »
Hello, I've got a big scene that eventually renders out fine and at full speed but the UHD cache and first pass or two only seem to work on one core and there is a lot of disk paging. I'm only using 55GB RAM out of 128GB and I'm not getting the virtualised RAM message either. So it seems Corona is prematurely looking ot page to disk. Any ideas why this would happen? I'm using corona 7.

Unfortuately interactive just crashes the scene so I have to render full frame to test and the UHD is taking 7mins which is a bit of a pain.

Also worth noting about this scene is that it can build right up to 80GB RAM usage when its first opened but then after a while it will eventually drop down to 20-30GB, so if I try to render straight away I get RAM warnings but if I wait half an hour the RAM dropsdown to more normal levels. Very weird. Wondering if its the slate editor hogging a lot of resources?

Thanks for any help anyway.

I find sometimes when my PC is under full load with a complex scene, having to click and hold the stop button to bring the drop down menu up to cancel the IR can be problematic and the UI lags with the potential of hitting stop instead. The problem with hitting stop is that it will save over a previously saved file which can be disastrous. Not sure why full render and IR share the same button set and stopping IR will trigger a save out of all the passes rather than just cancel it?

For years we have had really slow Max scene load times (45mins plus) Even on SSds and 10GB networks. These are big scenes with xrefs etc but still soul destorying when you have to restart after a crash. But we have recently descovered this autodesk script for which stops pop ups which was part of the problem. Even with silentium script installed Max still took a long time to load anything but at least you didnt have to manually click OK for popups. Load times are now about 5mins for the same scene!

Snag is I think its interfeared with the corona bitmap loader so you dont get the pop up box where you can load the bitmap. Is there any way of writing the corona bitmap loader to not be classed as a pop up like forestpack or railclone which still work with their own pop up dialogues? I know ideally it would be best for the script to ignore the corona request but I dont think autodesk would listen. Or if someone can edit this script to let corona through, even better!

Hoping this is the right section to ask. Is it possible to select one gpu for Max and another for photoshop in a dual card system? I have 2x2070's in my workstation but I'm pretty sure max and ps use the same one which eats up the vram and causes issues with working on big files in both. I originally thought if I plug one monitor in to one gpu and another monitor in to the other I could have max and ps use different gpus on different screens but pretty sure they aren't doing that.

Anything I find on Google just refers to switching between inboard gpu and discreet GPU but both mine are descrete so just want to select one for max and ps.

Thanks for any help with this.

I dont think this is possible at the moment. Any chance of being able to lock in the curves editor to the camera view like we can do with exposure? Will make it easier to manage scenes with several cameras that might need different curves settings.

Thanks

[Max] I need help! / Corona script error on Max launch
« on: 2020-01-07, 12:10:34 »
I've just started getting this error when I launch Max 2020. I have tried reinstalling Corona v5 but that doesnt help. The only other installation I've made recently is GrowFX v2 beta but I cant see how that would effect the corrona loading.

Corona still appears to work but the IR doesnt update. I need to stop it then move then restart it.

Im loathed to reinstall Max again if I dont have to so wondering if there is anything I can do to fix this? I might try the latest R6 daily to see if that helps.

Thanks

I've tried the new caustics on a few interior scenes so far and I cant seem to get clean caustics. The result is still what I would have imagined pre the new solver. I've attached an example below, 70 passes and the scene in general is pretty clean aside from the caustics. The main external glass is set to thin so that shouldnt confuse it. Is it designed for large internal spaces or more for small close up scenes?

Cheers

Hello. Railclone 4 has just been released and a good feature is now being able to get the materials from the individual segments rather than making an uber multisub and applying it to the railclone object. But it only supports Vray and Arnold. They say they have updated their API so any other render engine can add this support. Is this a possibility?

Thanks
