A map channel associates a map with an object’s mapping coordinates.
When you turn on Generate Mapping Coordinates for an object, the coordinates use map channel 1. You can assign new map channels with new mapping coordinates by applying a modifier such as UVW Map or Unwrap UVW to the object. Map channel values can range from 1 to 99.

I’m writing a script to effect selected bitmap and CoronaBitmap nodes in the SME and noticed that when you right click on the spinner it goes to zero when the default is actually 1.

this is 3dsmax limitation - all righclicks reset to 0, not to default :confused:

The corona bitmap filter spinner will beg to differ. It goes to 0.01.:wink:

4

0,01 = 0 in bitmap filter (Max and Corona). Enter 0 and it writes 0,01.

5

Oh yeah! so it does.. 0.01 = 1 who would of thought.

So in Corona bitmap this value ( 0.01 or 0 :wink: ) is disabling filtering and omitting the option the Max Bitmap has in the radio button?

I’m not and expert on that (nor programmer), but I don’t think these two things are connected. But maybe somebody with more knowledge will answer :smiley:

7

sorry, it is not reset to 0, but to the lowest allowed value :wink:

8

No problem. So to disable it completely there’s currently no way.

I know 0.01 is basically doing this but just curious.

9

afaik you can change filtering method from a dropdown to none…

10

That doesn’t exist. :confused:

I think Ondra meant the one in devel/debug rollout.

nearest neighbour should basically do the same, try it with filtering 0.01

edit: maru is right, it can be also disabled in devel/debug

13

Thanks Maru, I was aware of that but that’s a global setting and was thinking a bitmap specific one more-so.

That makes complete sense Ondra. Thank you.

I know this is old, but I am sitting here trying to understand what is the best way to approach the whole bitmap filtering and I am constantly finding conflicting opinions.

Also the DEBUG settings does not have an UI in the new 1.5 final build, so is it no longer possible to disable texture bitmap filtering? or is blur 0.01 practically the same?

Devel/debug rollout toggle has been moved to system tab → system settings.
