[Max] I need help! / Re: UVW Randomizer Issue
« on: 2022-09-28, 10:01:04 »
I often randomise the rotation of wood but with a Step value of 180.

Good point, but i think that wouldn't mess normal map, since XYZ coordinates would still match UVW.

Yeah I don't see the problem with randomizing the normal map in conjunction with the other maps.

Still a pain in the but that displacement doesn't line up properly.

[Max] I need help! / Re: Best Max system units for Corona?
« on: 2022-09-23, 01:58:08 »
If you for example always work on residential interiors, or products etc, then mm would be a good system unit.

But if you work on large exterior masterplans then you'll run into viewport issues when navigating your scene if system units are set to mm (and vice versa). So m in this case would be better.

If you work on both very large and very small scenes then somewhere in between is better, so I use cm.

Inches in theory would be better as it's even more 'in-between' mm & m, but I tried it a long time ago and it created some stupid problems so you should definitely avoid mixing imperial system units with metric scene units.

I've found for camera matching, the best way to get the specs from photos is to use exiftool. https://exiftool.org/

Drag a raw file onto the software icon and it gives you heaps of hidden metadata including the (horizontal) FOV.

And FYI if you're ever given a focal length that says 35mm equivalent, then you can leave your 3DS Max Film width at it's default 36mm. (the 35mm equivalent refers to the vertical dimension of film including the border, but it's still 36mm wide - a little confusing).
There's a big caveat though - if the photo was taken in Portrait, then whilst the focal length obviously remains the same, the film width in Max needs to be changed to 24mm (as the 35mm equivalent Full frame sensor is 36x24mm, so if you rotate the camera 90 degrees then (in Max) 24mm becomes the horizontal width of the sensor).

Example (from Mavic 3 I think?):

The tone mapping stack cannot be created from scratch using maxscript, or controlled using maxscript, unless you perform some manual intervention from the user interface first (e.g. create some new operators, change their values by hand). For example, if you create a fresh new scene and it already has some existing tone mapping stack, you will not be able to adjust its values using maxscript unless you change some of the values manually first. There are some technical reasons for this, and we did not predict that it could cause some issues to our users.

Could you explain in what circumstances my maxscript code won't work? So I know when I can just punch out all of my passes without having doubt? I just tried this on my base max template that has a tone mapping stack in it - and it worked.

And regarding ease of editing the code - if I want to add in an operator half way, is there an easy way to do this without repeatedly changing the Op, ID, and Property numbers for the whole script?

Thanks

As a temporary workaround, would anyone mind posting the maxscript for loading tonemapping settings that have already been saved out from the framebuffer?

Then I can manually save out the xml, and then I can hopefully use Vexus to handle loading the relevant one per pass. It's a real pain to update 8-10 or so parameters manually per pass without making any mistakes.

And the uninstaller is broke too so I have been stuck with Corona 8.

I'm an absolute beginner when it comes to Maxscript. Wondering if someone can help me to improve my script?

Background: when assigning object gbuffer IDs I am using a script to assign these based on my standard layer names. That part works fine.

However - there are some circumstances where I'd like to assign Object Ids based on a suffix on the layer name - for example "Layer01[OID16]" - and I wish to have a script that searches for the suffix and adds the appropriate ID.

Here is my script so far:

Code: [Select]
ObjLay = $.layer.name -- layer of selected objects

MyString1 = (FilterString ObjLay "[OID")[2] -- search the slected layer name for "[oid".  This is so I can add a suffix e.g. [OID7] to specify the Gbuffer ID I wish to assign.

MyString2 = (FilterString MyString1 "]")[1] as integer-- best I could do.

for o in selection do o.gbufferchannel = MyString2


I'm actually using this within Vexus (a nodal scripting tool for Max), and I already have another node that selects all objects on layers that contain "*[OID*]*"

The problem is this script doesn't work when I have different layers with different [OID] suffixes. I understand why it doesn't work, I just don't know how to fix it. I hope that makes sense.

10
Would anyone mind posting a couple of examples of how I might edit these parameters via maxscript?

I can figure out which I need to edit but I'm not a scripter.

11
The issue is present in my base max template too when I start a fresh scene.

12
Hi it’s not scene specific. Even my base max template does the same.

All material swatches are black too.

License server appears normal. Ie it shows when licenses are in use.

I can archive my template if that helps.

It’s like the camera is corrupted. Even maxes physical camera. It’s like the focal length has gone haywire.

Hi

It's within all views including perspective view & all scenes including new scene.

No I did not delete any files before going add/remove.

15
Here's what I get when I try and roll back to 7.

Via the Corona 7 installer & via add/remove programs to remove Corona 8. And if you hit ok it just goes in a loop and doesn't uninstall. Really hard to be objective here.
