[Max] Resolved Bugs / Re: DR strange shifted problem

« on: 2015-09-07, 12:04:47 »

I tried everything I think, removed all camera shifts, the example is using no camera just a perspective render.

There is definitely a bug related to perspective view and DR, I only can confirm that "pixel shift". Workaround for me was using a camera. Because of the fact that almost all scenes (including mine :) use a camera it may has been undiscovered by most people. Had no time to track the bug down and report it properly, but I sumbitted a similar report which is surely related to this problem on mantis already in April(!) this year - no response or even assingment so far:

https://corona-renderer.com/bugs/view.php?id=910

Well that was Corona 1.00 and I haven´t testet it with any current version yet.

You said, you had that pixel shifts also using a camera? Can you confirm that again?

As for your VPN: My Guess is that you have a routed VPN, not a bridged one so that network broadcasts packets do not reach all nodes (I think broadcasts is what Corona uses to find render nodes). This is a common setup to minimize network traffic. In this case the local network IP differs from the remote one and broadcasts do not work, you have to manually assign the IPs as you did it.

Good Luck!


P.S.: Topic should be moved to bug reporting -> dr bugs

[...] Is this 3d model or cutout person?

I guess it´s just a chromeball probe of his desk in the environment map. I would realy like to have probe projection in corona bitmap as environment mode. The only way at the moment is using V***-HDRI as far as I know. Please someone correct me if I´m wrong (I would like to be wrong in this case ;)

Good Luck

It´s always cleared after rendering, canceled or not.

[Max] I need help! / Re: Splitting Render into Smaller Tiles (3ds Max) - Best Practices?

« on: 2015-09-02, 10:18:58 »

[... ] Neither reduced the appearance of the seams.

Back in dark win32 ages with 2GB limit I found a very basic line of code, extended it and wrapped all into a Maxscript GUI. This script uses rendermode #blowup + region.

I don´t know who had this idea in the first place so I will provide the full script here for you and others.

I just checked it with corona and it seems to work. Haven´t used it since Win32 times so there may be improvements to do. I can faintly remember that I always had issues with standard #crop and for this reason changed to #blowup + region (I don´t think it´s a corona problem you have. What´s the result using scanline renderer?).

Restriction of the script is obviously that number of tiles x and y are always the same. So in your case you have to render 768x510 with 9 tiles.

Good Luck!



Edit: Attaching v2.21 where UI size cap is raised to 2^16 (65536). Will maybe revisit this in 10 years to set it to 2^17 :)

Probe projection? Who use mirror ball made hdr maps anyway? :]

Me. To some degree. It´s not about HDR but it´s the projection I need:

For quick´n dirty reflections we usually take a single photo with a circular lens. Take a photo, extend the canvas in PS or whatever application so it meets a mirrorball FOV and plug it into a shader supporting mirrorball projection - ready. No conversion, no stitching, no postwork for the environment at all - just one photo. Enough for reflections when you do e.g. archviz projects where the counterpart is important and would be (and should be) visible in reflections.

Right now VRayHDRI is the only way to do that in Corona afaik, please correct me if I´m wrong. I´d love to see "Mirror ball" in the Environment mode dropdown of CoronaBitmap for this reason in the future.

Good Luck

[Max] I need help! / Re: Corona proxy is transparent

« on: 2015-08-10, 19:45:38 »

Besides a possible gamma issue (maru already gave you the corresponding links) do the following:

- open a maxscript listener window
- type "ATSOps.CheckNetworkPaths=true" (+Return)
- It should say "true" printed in blue
- Open Maxmenu -> "References" -> "Asset Tracking"

and have a look at your paths. I bet you will find your IES file(s) linked to a local/non accessible path for the slaves. It has to be a network path with access for all slaves. Otherwise you will lose your IES lighting. Same goes with all other assets like bitmaps. Even if you see a "Found" there this may indicate something is not correct. "Ok" is what you like to see there :)

This is a very basic standard procedure when things are going wrong with (any) dr/bb issues.

Good Luck.

Rawa, I agree in 1. and 3 and that it should render(!) exactly as the final render. But I presume no one at all uses IR for final production but for quick tweaking. And it does it´s job so perfectly (now that a lot crashing causes get fixed),  that´s in fact unique.

So at least the ALT-Q part is very questionable for me. Consider for example the god ray tutorial where there is alot ALT-Qing. If the scene would have any Xref scenes attached (e.g. the arch xrefed out), it just would not work to have a table quickly isolated to tweak/modify it and then check it again in the complete scene without switching on and off the Xrefs every time. There are various reasons to xref stuff out - I don´t have to tell you.

My dream is that one day Corona IR will allow us for workflow similar to these videos: https://www.youtube.com/user/evilmrfrank/videos

Fantastic! But dream on :) Not with Max as host application. Never in this universe :]

Good Luck!

This is no "fix", it´s a workaroud (and even a very bad one) for your messed up proxy paths / access rights / network config. How does the failing proxy paths look like?

What may has to be added to the Dr guide is a section about asset paths (and a hint to max asset tracker), unc vs. mapped drives and user rights. There are just a few things to respect.

Good Luck!

Funny, just yesterday I was considering submitting a "feature request" like that on Mantis but I didn´t wanted to spam the Tracker with stuff like that. So I think it´s a good idea to discuss it here first.

My contribution to this topic is attached. Maybe there is some reason to have this checkbox but I thnk it could be removed.


Good Luck!

[...] a shared network folder that I have mapped as X drive, so that can't be the problem.

It can. If you don´t use UNC-paths and run your BB-server as Administrator or just as another user (system or whatever) that account may not even has your "X:" drive mapped. A good way to check this is to run BB-server interactively as the current (logged in ) user who has your drive mapped already. But I presume you already tried this.

Good Luck!

If it updates fine in Max viewport but not in IR, then it's probably just another bug ;)

This leads to the very basic question: what exactly should be rendered by IR?

That what you see in the viewport? Or: That what would be rendered when you hit "render"?

The three key situations for me are:

1. When you have a Xref scene (for me still the one and only way to assemble large scenes) and it is not set to "Visible" in the Xref Scenes dialogue so that you don´t see it in the viewport. Should it be rendered in IR? At the moment it does render that Xref scene.

2. When you ALT-Q something (isolate it): Should the other non isolated objects be rendered by IR? At the moment it does not (but still any xref scenes!)

3. When you do a "Hide by category". Should the hidden objects be rendered by IR (and by standard render, but that´s another topic which hopefully will be discussed some day)? At the moment it does.

Isn´t IR meant for quick tweaking/previewing? For me personally it should always only render what´s in the viewport. So the behaviour for every of the three situations is not what I would like to have for a quick preview tool (IR).

[Max] I need help! / Re: General question about very glossy refractions vs. speed

« on: 2015-07-03, 10:46:59 »

you CAN use translucency on "thick" objects in Corona, right? I'll try that too.

Yes, right. And it looks more realistic/interesting so I wouldn´t deactivate the shell mod. What´s that background in your scene? Maybe something other is causing the noise (background/floor material) - I would tweak/test in a neutral environment.

The attached scene (for further testing if you or someone else wants to) is pretty clean after 150 passes / 1k. I even activated reflection on the floor and on the cubes material.

Good Luck!

Do you need refractions for some reason? I´d use translucency only if not.

Good luck!
