[Max] Resolved Bugs / CGeometry_ZDepth Not Saving in CXR Format

« on: 2017-09-22, 15:41:41 »

I experienced a bug saving my Z Depth pass. When saving CXR format from Max, the z depth pass falls out of the file, not present in CIE. Also not present when auto saving individual passes to CXR from batch render. I have to save this individual pass out from the Corona VFB inside Max.

I haven't tested other CGeometry passes, but I can say for certain there's an issue with CXR including z depth. It has occurred on files saved from the 9-15-2017 (first 1.7 daily I tested on my office workstations) daily to RC1.

[Max] I need help! / Corona VFB behavior - Is this Normal?

« on: 2017-09-19, 15:01:50 »

This may have been discussed already but I installed the 9-15-2017 DB and noticed the VFB behavior with the scroll wheel has changed. When I zoom in to investigate my rendering, see how details are rendering, I can't scroll out with the scroll wheel. It just moves the image up or down. I have to use the magnifying glasses to zoom out. Is this how the VFB is functioning now? If so, is there a way to change the zoom in/out back to the middle scroll wheel? It's a minor thing but I've already found it cumbersome to view my image while it's rendering. Part of me thinks this is a bug though. It isn't always functioning this way, it's very odd.

[Max] Resolved Bugs / Refraction Not Rendering Properly in DB 08222017

« on: 2017-08-26, 21:26:14 »

This was from a simple dispersion test. Very first time loading the new daily for 1.7. I made a refraction material, then clicked dispersion. Instantly it rendered wrong and then materials wouldn't change in IR after changes. As if the refraction is visibly 0 but light still passes through it despite appearing solid.

I was able to replicate this just moments later in a new file. Initially it loaded as I would expect, but after a few material tweaks, IR stopped refreshing with material changes and then it started rendering without any refraction (but with thin checked it worked fine).

Has anyone else experienced this issue? I literally can't get past one material adjustment in the new dailies.

[Max] I need help! / Strange Shading from Env Lighting for Interior

« on: 2017-07-15, 21:35:57 »

See attached. My scene is throwing some strange shading from the environment lighting. I'm using all corona lights with the exception of a few target lights from a converted model. But that light select pass looks perfectly fine. Does anyone know what's causing this? The issue seems attached to env lighting, using the Max environment or Corona, provides the same issue. Use of Corona Sky, solid color, or HDRi still provides the shading issue.

I have a deadline Monday so it's critical I resolve this. Any help would be appreciated.

[Archive] Chaos Corona for Sketchup / Installation Question

« on: 2017-06-21, 16:04:47 »

I'm trying to install Corona for SKP but am having issues. I run the installer and it seems to install as I would expect. I ran it as typical installation and I get it to report all is successful. Then I run SKP, nothing installed. I then run custom installation, select SketchUp 2017 but get errors saying the install path hasn't been defined. I unpack the files and copy the files to the appdata location of my SKP plugins and also in the /Corona/Sketchup/plugin folder. I only get errors now, see attached.

This exact same scenario has occurred with the 2016 version. I gave up trying to install this before but receiving an email saying a new installer was available gave me hope. Can I get some instruction on specifically where these files are to be copied or what I'm doing wrong?

Thanks!

[Max] I need help! / Prevent Black Appearance Not Working Properly on Rectangular Lights

« on: 2017-05-22, 20:25:28 »

I'm not sure if I'm the only one who has this issue, but I can't seem to preserve the direct appearance of rectangular lights. The prevent black apparent just doesn't seem to work in these instances. Is this normal for rect lights?

[Max] I need help! / cVFB Behavior during IR, Options?

« on: 2017-05-10, 17:01:32 »

The Corona VFB is designed to increase window size to the fit the render size, depending on the zoom. This is great when I'm running a production rendering, but I very frequently zoom in to focus sampling on a small area during IR. When I click back in the VFB after modifying something in the viewport, my window expands to a huge size to fit the zoomed render and restarts the IR. At a size that spans multiple monitors, commonly the rendering jumps to ~3k-4k wide. It's extremely frustrating. Is there a way to disable this in IR or do I just need to be more careful not to click inside the VFB?

Work in Progress/Tests / House In The Woods

« on: 2017-04-14, 05:35:44 »

Hello all,

Here's a personal project I've been working on. I haven't been very social here so I thought this would be a great way to start. I'll try to keep updates somewhat regular.

I have been using this as an opportunity to try using 3d scans and Forest pack to create the woods-y environment. I will be moving on next to bringing the house up to speed. The interior hasn't been modeled so the house was best rendered white. There's also a heavy dose of ArionFX on top of this, another plug-in I've been trying out.

Let me know what you think!

[Max] I need help! / Saving EXR with Background

« on: 2017-03-16, 12:59:22 »

This might be a stupid question and I couldn't find an answer by searching. But is it possible to save an EXR format without the alphas being applied to every layer? I recently started saving my image as EXR and didn't encounter this issue as I started with interiors. Now I have an exterior shot, I can't for the life of me open the file in Photoshop without losing my background. On all render elements.

I use EXR-IO and maybe this is the issue. I haven't tried ProEXR. There is a dialog box upon opening my EXR and if I check "Fix transparent emitters", I get my BG, but on an extremely low opacity and I need to flatten that layer onto a black layer in order to see the background properly. Obviously this isn't ideal but I'll do it if I have to. Am I doing something wrong or is this the nature of EXR format?

[Max] Resolved Bugs / [feedback] Strange Black Artifacts on Surfaces/Edges

« on: 2017-01-16, 22:16:27 »

I was rendering an extremely simple scene with some test geometry. Everything was going perfectly fine, and I added an additional geometry and now the file is permanently wrecked.

See attached for the normal image and one with black artifacts, as well as the Max file.

I'm using DB Dec 13th 2016 and Max Design 2014. I have never had this issue before.


I decided to do a test on a new scene, with default render settings, and the issue appears to be with Corona, not my scene. See "box-same_error". I'm on my work machine and don't have admin privileges so I can test rolling back to an older build until tomorrow morning. Has anyone seen this problem before?

** Update: This only happens in orthographic mode. Which I've always had issues seeing things in interactive while using an ortho view, so this is nothing new. But a bug none the less

[Max] I need help! / Loading Corona EXR into VFB

« on: 2016-10-25, 16:18:59 »

I'm curious if it's possible to reload a Corona EXR in the VFB and have control over exposure, lightmix, etc after other images have been rendered. This would be ideal if I were to run a batch render of several views and I could open the EXR to correct any lighting issues. If this has been discussed at length I apologize, I haven't found the thread.

[Max] I need help! / Slow GI Precomp and Even Slower Initial Pass

« on: 2016-08-23, 14:14:23 »

Hello,

I'm currently trying to render a dusk, exterior scene. I'm experiencing extremely slow precomp and render pass times. This is very strange because prior to trying to render for production, I was able to render the same file, at any resolution, rather quickly. I restarted my computer to prevent a restart overnight due to updates, installed whatever Windows updates were available, and now I'm unable to render my file.

I'm currently using Windows 7 Professional, 3DS MAX 2014, and the Aug.19.2016 Daily Build of Corona. Attached is a screenshot of my stats from the VFB. My machine is running 2x Xeon e5-2680 v2 processors, 64GB RAM, and a Quadro K5000.

The only thing I could think of that could be the culprit is my multiple ForestPack objects. However, this scene was rendering perfectly fine prior to restarting. Even with an interactive viewport to correct lighting values (scene originally created for V-Ray 3.3). I tried running the same build of Corona in MAX 2015 but still with no luck. Tried PT/UHD and PT/PT, no improvement. No errors from Corona. i'm going to try running the 1.4 build once my IT guy gets in this morning (damn work computers and locked up privileges). Maybe that will help the issue?

I can provide more information if someone can direct me how.
