[Max] Resolved Feature Requests / Affect Diffuse Feature in Corona Lights which is available in Vray

« on: 2024-06-08, 20:14:36 »

at my workplace we have both Vray and Corona and one of the features that I would love is affect diffuse checkbox in corona lights

whats the use ?

my work is mostly related to products and many times I want to reflect a specific reflective part of the product, in Vray I simply put a light directed towards the part I want to reflect and turn off "affect diffuse" along with visible in renders and occlude other lights and so what happens is only the reflection channel is affected which means the parts around the glossy area won't have blown pixels and I can perfectly adjust the light without worrying about it destroying my lighting affecting other parts

what happens on the other hand in corona is I have to play with different light positions, different IES profiles for sometimes hours and it's still not quite close to what creative freedom I get in Vray

many of you might suggest to change the angle of camera or the product so that It can naturally highlight without faking it but most of the times I am blocked from changing those aspects hence why I am making this request

Thank You

There is this:
The message “Error Creating File Output”: caused by 3ds Max bug that adds non-existing paths to render elements.
Solution: go through your render elements and delete all non-existing output paths, or fix render element paths in the asset tracker (Shift+T).

But it would be great to know that your actual error message says. A screenshot would be great.

Thanks maru but we have tried doing that as well, when I'm setting up file to render high resolution what I do is put render path and file name in common tab and then refresh render elements by loading up a preset and choosing only render elements, then I check it with asset tracking to see if all the path that we entered are correct

and the actual screenshot, I'll have to ask but I'll try to get it posted here if possible

It might be related to a couple of reason, having the same heading, can't write the file for some reason.

I've had the issue once with PNG files, apparently due to "some corruption" in the PNG I/O plugin.
It might happen simply because the program can't access any of the folders it has to access at the time of saving. Not only the output files but sender elements or God knows, whatever configuration file that has to be read or written and can't succeed.
The frame of such errors can be so wide that you can experience things you can never imagine. (Even the folder name length exceeding 256 characters cause problems or some Unicode character that doesn't represent a valid equivalent for the OS.)

3DS Max Batch system is also not so intuitive. I enter parhs, file names but at the end of the day, find some XXCamera _View 01 like naming scheme which I could never figure out how I have achieved that.

This is very probably Max issue, and in the Vray instant, you probably didn't have the same thing causing the problem.

having the same heading, can you elaborate on that

and for format we usually use 2 formats, Jpeg and TIFF and we experience this error on both formats, and out path names are also within 256 characters, in cases where it exceeded we were notified before the render begin ig

as for batch plugin, yes it might be the issue as well but in another firm uses network rendering and they never ever had this issue appear,

and it being a max issue, absolutely possible but I have little to no hope of getting it fixed from their forums since most of my coworkers have to go to other sites to find solution to things that were asked on autodesk forums

Maybe totally unrelated but I recently had a similar problem where exr files would throw an I/O error and not save.
Turns out it was an Umlaut in the path name and the solution was to remove any non-english characters in the path or filename.

I see, but unfortunately we have only english characters in our file names

Which batch render plugin you are using?

What version of 3ds Max and Corona you are using?

Are you saving the files locally or on network drive?

I don't know the batch render version but it's not it's fault, because earlier we used to open 4 3ds max and start rendering in all of them at once, and we would still get this error

3ds max version 2022 and corona version 9

files are currently on network drive but I don't remember if we had same issue in local saves

Hello,

so in our team we use bath render plugin to render multiple renders overnight, and what ends up happening is let's say we put 4 files in rendering, when the first one ends it shows the image i/o error, it not only doesn't save  that render but also stops other files from staring rendering, so in whole night only 1 render is completed and other 3 renders are still pending

we tested it with Vray and it never had an issue with that, i was wondering if its a bug or we're doing something wrong

what we have done so far is, put path in common tab then updating render elements and checking it in asset tracing to see if both path are same and the folder exists, we have checked it many times and it's correct yet this error is unavoidable

we render usually in 6k x 4k resoultion in TIF format, on every machine theres 48-96 gb of ram available so we extremely rarely face any low on ram issue

Any hint or any workaround would be extremely helpful

Thank You

[Max] I need help! / How to create Marble or Ceramic look like this with SSS

« on: 2023-05-29, 11:16:12 »

So Poliigon recently dropped a trailer for their Marble Textures and the way it's shown in it, it seems like they used SSS because I work in field related to ceramic and the difference is a lot, I'm not sure which software was used to make the trailer but I feel like it must be possible to do in Corona as well

I tried a lot but everytime I compared my renders to the one without SSS the only notable Difference I saw was in render times and nothing else changed visibly

What I tried fiddling with was I used the SSS marble material from XSMP Shader and use the diffuse as Marble texture and then tweaking the settings for SSS

Here's the link to that

Please Let me know if I made any mistake in posting it

Thank You
