Please fill out Blender experience questionare.

Warm-up and get familiar with the interface.

30.9. Mesh Modelling Fundamentals

Trying out mesh edit mode and editing tools.

Practical home assignment [2 bonus points]

The project is focused on practicing techniques of modelling and rendering learned on exercises. It is split into two stages evaluated separately throughout the semester.

Note: Accomplishing bonus tasks grant you an additional points, but cannot get you over the maximum of 100p from exercises.

Stage 1

Deadline on Sunday 15.11.2020 at 23:59

Goal of this project stage is to create models for interior "room" scene.

Find reference images for objects and model them using learned techniques.
Create 2 objects from each modelling category:
Simple Polygonal: apple, lamp, book, chair, etc.
Curve: light bulb, vine glass, candle holder, corkscrew, etc.
Create 1 object from each modelling category:
CSG: mug, ashtray, bowl, etc.
Blobby: candle, toy (teddy bear, dino, ...), etc.
Use correct modelling techniques for each model category (20p)
Simple Polygonal: extrusion, inset, loop cutting...
Curve: curves, screw modifier...
CSG: boolean modifier, parenting, object hiding...
Blobby: metaballs, negative influence...
Complexity of selected reference and modelled detail (15p)
Editing friendliness - not applied modifiers, low polygon count (10p)
Aesthetic of created models - proportions, realism, etc. (5p)
Before modelling create folder named "mrt_p1_[your name]" and place all files inside that folder.
Each model should be located in a separate collection
Folder should contain ONLY ONE blend file and object reference images
Pack folder to archive (zip/7z/rar) and send to with subject "MRT Project 1"

Stage 2

Deadline on Sunday 5.1.2020 at 23:59

Make a believable interior scene of a room by your imagination. You should use models created for the previous project stage, and create some new ones, or use any publicly available models. All materials should be designed by yourself using the node editor.
Create custom UV mapping for 3 complex models. (12p)
Correctly set up materials for the entire scene (10p)
HDR environment map (5p)
Textures used to control at least 4 material parameters (5p)
Used at least 2 procedural textures (5p)
Used displacement map (5p)
Scene logically separated into collections (3p)
Aesthetics and believability of final renders (5p)
Bonus: Use 2 textures edited/created by yourself. (2p)
Bonus: Use compositing node editor to create final touches to renders: bloom, color and contrast adjustments, etc. (3p)
Before modeling create a folder named "mrt_p2_[your name]" and place all files inside that folder.
Folder should contain ONLY ONE blend file and all required resources as well as final renders.
Create a text file in a folder and write down notes - which models are yours, which UV coordinates you created, which textures you edited/created, etc, to distinguish what was downloaded and what was made by yourself.
Pack folder to archive (zip/7z/rar) and send to with subject "MRT Project 2"
