[Max] Bug Reporting / Collab -in VFB causing "internal error meesage"

« on: 2025-05-10, 20:29:32 »

When rendering a Scene and accidentally hit "collab" instead of "Lightmix" the rendering stops with "internal error..."

This is kind of troublesome. After this render failure - you need to close max completely to start a new rendering again. Is there a way to let this "Collab" tab disappear - when you're 100% sure you will not ever use it?

[Max] Bug Reporting / Forrest Pack and Lightmix/Select not working in Corona 12 update 1, as before

« on: 2024-11-22, 15:53:25 »

Recently i installed Corona 12. update 1 and it doesnt render specific light objects (various Polygonobjects with corona light material) in each of their own Light-Select Renderelement - just the main ForrestPack_Object containing all light objects when added to a light-select element.

Before corona 12.update 1 it was behaving that way

FP-object containing multiple Lightobject A and Lightobject B

in Corona 12 hotfix 1 and lower
Lightobject_A --> Lightselect_element A = light only A
Lightobject_B --> Lightselect_element B = light only B
FP-object --> Lightselect_element_FP = dark no light


in Corona 12 update 1
Now those individual light-objects get ignored and it only renderes the FP_object
Lightobject_A --> Lightselect_element A = dark no light
Lightobject_B --> Lightselect_element B = dark no light
FP-object --> Lightselect_element_FP = shows light of A and B combined

This is actually something that makes postproduction very complicated if i cant separate light-sources in Light-Selct / Lightmix anymore... and need for each light-object an individual FP-Object to be created.


Not sure if thats something the new corona verison messed up - or if its on behalf of updated Forrest.Pack

max 2025 / corona 12 update 1 / ForrestPro 9.1.5

ps. It does work with max 2024 / corona 12 hotfix 1 / ForrestPro 9.1.5

So i doubt its caused by forrestpack.

[Max] Bug Reporting / chaos cosmos problems

« on: 2024-09-27, 09:36:42 »

Hello,
when using Chaos Cosmos Materials (the soon to be standard for corona materials) I get various Error Messages when rendering.

Specifically with concrete grey 03 ... but i bet its a common problem with chaos cosmos objects or materials.

In this Case i get an error message, that Normal maps have incorrect gamma. Even if i apply / or remove "add gamma to input" the error message will be the same.
Since the annoying use of .tx file format, its not possible to alter the files in Photoshop to replace the input to get rid of the error-message.

I don't like to have error-messages everytime i render - then the real errors will be overseen.

Other than that - if chaos is basically forcing everyone to use chaos-cosmos (out of additional revenue or whatever reasons) then it would be best advised to proper manage that library and be sure that even with new releases of rendern-engines the assets are up to date and working.

[Max] Resolved Bugs / corona 12 VFB 2.0

« on: 2024-07-21, 08:07:27 »

Is it a normal behavior that heavy scenes (corona warning memory etc) rendered in corona 12 vfb2.0 will be unresponsive as long as the rendering happens?

So far i experienced when doing IR i can set up lightmix and switch between renderelements. When rendering production i'm unable to do anything in VFB2.0 ... it even stays black (showing nothing) unless the max "rendering progress" dialoge is moved by mouse.

I've not yet tested corona 12 with the old vfb and if the experience is the same or as it used to be before corona 12.
--- I did a short test with chaning vfb 2.0 to vfb under system settings. But it showed no difference - still the issue with black vfb as long as you move the rendering dialoge, also no interaction with vfb possible.

[Max] Bug Reporting / Cshading_component and clearcoat

« on: 2023-12-15, 19:37:36 »

I have recently stumbled, why my Cshading_Components is showing Reflections again - even though "reflect" was turned off in "include material components"

Recently i found some materials showing reflection in "cshading components" ... there were mainly new corona 10 or corona 11 phsyical materials -  maybe because of clearcoat. But i can't really figure out, why they show up in reflections, even if i turn off clear coat.

ps.
I realized when using old legacy materials, the reflection won't show in "cshading_components"- when reflection is turned off in "direct/indirect" ... it does nonetheless, when i use physical materials.

General CG Discussion / Chaos website - corona invisible

« on: 2023-03-08, 12:21:07 »

Hello,

I recently was a bit confused not finding any link or information about corona-renderer on the main chaos website even not on the product page or ecosystem.
https://www.chaos.com/ecosystem

Enscape and Vantage is listed as well as chaos cosmos etc. and even cylindo has a prominent link at the bottom of the pages - so why not chaos corona?

Is this a business decission not promoting chaos corona in favor for vray or the other solutions? *
Feel its a bit odd to just know the "corona-render.com" when its basically another product of chaos.

[Max] Feature Requests / Output Autosave - settings reset after new version installation

« on: 2022-11-02, 17:08:03 »

Hello

I might suggest that keeping the Output Autosave settings, when installing new corona versions (or reinstalling)
Figured it will be always reset once I install a new version.

Its a bit annoying when you forget to check the settings when rendering and realize later you have set the wrong file format. With Autosave you still could resave everything vom CXR.... or in case a power outage happend and at least you get the last autosave version to work with.

[Max] Feature Requests / ToneMap Control for Sky-Volume

« on: 2022-09-19, 15:16:54 »

Is it possible to add a function to disable "sky volume" on images with "tone-map control" ?

Would be useful if you use  camera mapped image as background (on plane or sphere).

[Max] Resolved Bugs / Diffuse map not showing in Material Preview when using composit-map

« on: 2022-07-07, 10:01:57 »

Hello,

Not sure if that is something i never noticed, or some weird bug. If creating a corona-physical material. The Material preview is not showing the base/Diffuse layer if texture map channel is other than 1 if i use a composit map to mix various texturemaps.
All other maps like glossy or bump show correctly.
I probably didnt noticed, when i used straight the map or with legacy materials.

I'm using Max 2020 and corona 7 hotfix1

[Max] Resolved Bugs / Corona 7 UV randomizer and displacement

« on: 2022-05-13, 17:13:49 »

Hello I still struggle to get corona uv randomizer with displacement and multiple elements to work.
It always is random offset to each map.... even though the uv-randomize settings and seeds are exactly the same

Is it still a known problem or is there something wrong on my set-up?

I'm using latest corona 7 release with max 2020.


It looks ok - if i set everything in the uv-randomize-map to "no randomize values"

[Max] Daily Builds / propagate reflection/refraction

« on: 2021-04-29, 15:29:24 »

is there a specific limit, on how much elements the "propagate masks" feature is working?
I tried the latest build of corona 7 (april 21.) and still get this behaviour, that after a few objects containing the specific material, the mask is appearing again.

Short Testing: issue appeared after 5 Elements (with 2 sides) ... so in general 10 transitions.
Is there some value in rendersettings which has an influence on this number?

[Max] Bug Reporting / CoronaColorCorrect and Bercon-Tiles and Multitexture

« on: 2020-10-29, 09:35:11 »

Recently i started using Corona 6 hotfix 1 on 3Dsmax 2018/2020 and realized some textures won't appear as previously set up in corona 5.

I was using a Material with Bercon Tiles and Multitexture maps - put an Corona Color Correct in between.
When using CoronaColorCorrect the Texture isn't mapped properly.

Wen overriding the CoronaColorCorrect it appears as it should be.

Originall i was using the CoronaColorCorrect to alter the appearance of Textures before applying Bercon Tiles... so Gaps/Edges appear differently than the tile texture.

[Max] Feature Requests / Environment - multiple maps (Lightmix) - Mapselection for Renderelements

« on: 2019-12-18, 16:37:58 »

Is it possible in RenderElements (like CShading_rawdiffuse etc) to chose which of the maps from (multiple maps) has an effect on?
Right now if i render with 4 different maps - they all affect the renderelements - there is only a selection for LightSelect-renderelement.

Or is that technically not possible - and i need to run 2 rendersessions - one with those multiple maps - and one with my preferred Environmentmap for all other passes?

[Max] Bug Reporting / autosave feature...

« on: 2019-12-08, 14:37:16 »

its a bit confusing, that you have the choice to autname the files "_%v" (or like that) ... but the nr. of kept files will even delete "autosaves" with different namings.

Feel a bit disappointed that i lost a complete CXR-autosave file from a different camera, after a batch-rendering.

[Max] Resolved Bugs / Color Tint resets to blue

« on: 2019-06-21, 13:10:04 »

I today realized the Rendering is appearing in a blueish color tint? Seems like if i do batch-rendering the color-tint resets to a blueish tone each time.
Not sure what it caused it - just started to appearing in various scenes it did worked correctly a week before.

Only thing that happend was the occasional Windows Update and installing of a new Wacom Driver.

Corona 3 Hotfix 2 and 3Dsmax 2018 latest update.
