MODO noobs & hobbyists

So, you're an avid part-time MODO user, but you'd still like to be able to keep up-to-date with all the neat tricks and cool ways you can optimize your MODO workflow.

Being a hobbyist sometimes it can be weeks or months before I manage to find some spare time to mess around with MODO, by which time, I've almost forgotten everything. :-/

This site is just as much for me as it is for you. It's a place where all can keep all the tips and tricks I come across, and it's fully indexed, so you should be able to find whatever you're looking for very easily :)

I'm no MODO expert - far from it, but every other month I'd like to be able to present you with a new article that'll become a new string to add to your modo bow.

If you're a longterm 3D artist or professional, then I can't guarantee there'll be much here you don't already know. You can always have a poke around though., or if you are looking for something specific, use the Search menu up the top (and the links with topics, categories and tags underneath) to find exactly what you're after. If you don't have any luck, let me know if there is anything in particular that you're looking for.

Searching for missing texture image files on Macs

Description

When modo first opens an .lxo file it tries to look for any texture images attached to that scene. If you happen to move your scenes across different machines that have different paths set-up, modo won't always be able to automatically find your texture files. Instead, sometimes it will ask you whether you want to search for them.

Because modo stores image textures under the \Library\Application Support\Content\Assets\Images,  if you try to locate a file saved here using Spotlight, you'll get no results because that folder is restricted from being searched. Two ways to get around this...
Step-by-Step
    • Navigate to your Contents folder and then perform the search, narrowing it down by folder and file name. I actually have a link to my images folder in my Finder sidebar
    or
    • In the spotlight search bar, type in  Filename:"brick_bump.png"

Do you get gamma?

Problem

When applying images to a surface, they may appear in the rendered frame as being a bit too light or washed out. This is because modo always renders internally at gamma 1.0 (linearly), and then applies the user's specified output gamma when displaying or saving the rendered result. 

Bitmapped images typically have automatic gamma applied to them in an image editor or digital camera (otherwise, they would look too dark to most users); and because of this, rendering with modo’s default gamma value (2.2) will make your images appear light or washed out as they have received double gamma. Therefore, it is important to de-gamma your images.

Solution

This can be done by inverting the gamma amount, simply by dividing the Render Output gamma amount, whatever it may be (but 2.2 is the default), by the image map's item 1.0 value.

This can be done directly in the value input field using mathematical shorthand. For instance users can simply type “1.0/2.2” into the dialog box and press enter, and it will return the value “0.4546” (modo does the math for you!). Now the rendered image will produce the correct result. 

 

And if you are interested in a general understanding of gamma and how it works on your computer, Richard Yot has made this video that might fill in some of the gaps.
