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.

Aligning silhouette people to the Camera

Description

Architectural visualization is often known for its silhouettes of people going about their day. These 2D stencil images can be downloaded from the 'net, or from the MODO asset share site. When it comes to changing camera angles though, it's not necessary for you to go around and tweak each person so that they remain aligned to the camera. Here's a trick I saw Brad Peebler do a few years back.
Step-by-Step

  • Under the Animate tab at the top..
  • in Item mode, select the silhouette Mesh, then Shift-select the camera
  • click on Direction Constrained in the Modifier section

 
Render-Backwards                

You'll notice then that when you move the camera, the 2D Item Mesh will always align to the camera. However, one thing that you probably won't want it to do is, tilt when you move the camera up or down. You just need it to move on the Y-axis only

Render-Backwards
             
  • On the righthand-side, under the Properties tab..
    • click on the Direction Constraint tab
    • click on Add output Options
    • change the Opacity on both the X and Z axes

How to create condensation

Description

In November 2014, I had the privilege of organising and attending the SWEDEN LOVES MODO event in Gothenburg. I learnt a lot that day, but the one thing I took away and wanted to be able to reproduce when I got back home was an example from a presentation by Paulo Madeira on how to quickly create condensation / water droplets on the outside of an object, like say, on a can of coke. 

Now, if you have tried this exercise yourself before (or using a preset from the Asset Share site), you'll probably recall that it took a lot of resources, and your render times probably went through the roof. Paulo's method takes all those headaches away with a few clever tricks he's come up with. 
Step-by-Step
 

In Paulo's example, he used the Chameleon preset that comes with MODO. So for the purpose of this exercise, we will too and assume you have setup your environment and lighting. 

  • Drag in the Chameleon mesh preset.
  • In the Shader tree, delete the preset textures that came in with the mesh, but keep just the 'Chameleon on Branch' folder.
  • [dcs_emptyspace h="20"][dcs_emptyspace h="10"]Create a new material and set it to a vibrant colour.
  • Right-click and duplicate the Chameleon Item Mesh and rename it Droplets.
  • Apply a white material to the Droplets mesh and call it Condensation.

As there are now two meshes located in exactly the same space, turn off the original Chameleon. You will then see just the droplets material.

  • Inside the Condensation material, go to Add Layer and insert the Pebbles texture (under Enhance:MODO Textures, Noise, Pebbles). The white areas will be where the droplets will appear on the mesh.
  • [dcs_emptyspace h="20"]“Pebbles-Texture"</span></li><li style=" width="“294"
  • " height="“352"
  • " />[dcs_emptyspace h="20"]To resize the droplets, go to the Texture Location tab under properties, and change Size X, Y, Z to 15 mm each.
  • Under the Condensation Material change the Displacement Distance to 2 mm.
  • Change the effect of the Pebble texture from Diffuse Color to Displacement.
The Pebble texture covers the entire mesh, however, you only want the droplets themselves to be visible, so you will need to make those parts that are not actual bubbles, invisible (i.e. the areas which lie flat against the skin).
  • Duplicate the Pebbles texture, Invert it, and then change the Effect from Displacement to Stencil.
  • With the Pebbles/Stencil effect texture selected, under the Texture Layers tab, increase the Bias to 100% to make the transition of the edges of each droplet sharper so that they touch the skin surface.
  • Turn on the Chameleon mesh to view the results so far.
  • To make the droplets transparent, apply a Water preset material (i.e. remove any displacement or bump layers) to the Condensation material. Drag it below the two pebbles textures.
  • Change the Displacement Distance to 2 mm
To make the Chameleon metallic like Paulo did, change the material to 0% Diffuse, check Conserve Energy, Specular 20%, reflections 80%, check Blurry reflections.
