No problem at all, thanks so much for the advice. Do you happen to know where I can not necessarily train, but simply purchase a custom LUT? (I already have a plethora of free LUTs but i'm looking for something much more specific)

Here’s another one, there’s so many online anyway, plus you can make LUTs from Lr.

I build Tessellations using Affinity Design in normal mode (not Isometric).
To do this, I create Shapes, adjust their size + arrange them to build a Pattern:
So that the Shapes snap within a Pattern and so that the  Pattern when duplicated, snaps within a Tessellation (as demonstrated in the 3 images below)   
Below I describe my workflow followed by questions looking to make my process more efficient. 
 
WORKFLOW
Step #1 - Find Shape Dimensions for Pattern
To find the dimensions of the Shapes within the Pattern, I:
Create the Shapes, then I Adjust the constrained size + Rotate + Move the Shapes so they snap to each other (this provides the necessary Shape dimensions to fit within the Pattern)  
Step #2 - Find Shape Dimensions for Tessellation as well
The dimensions of the Shapes must snap within the Tessellation too - so I:
Duplicate the same Pattern (from step #1) as many times necessary so the duplicates fully surround all sides of the Original single Pattern, then I Adjust the constrained size of the Shapes so that all shapes snap to each other within both the Pattern + Tessellation (this provides the Shape dimensions within the Tessellation)  
Step #3- Erase the erroneous, extra Shapes that don't fit within both the Pattern & Tessellation
Once the Shape dimensions are final (they snap within both the Pattern and the Tessellation), I erase the erroneous, duplicate Patterns, keeping only the Pattern with the correct Shape dimensions that snap within both the Pattern and Tessellation.  
 
Step #4- Merge the Patterns into images rather than shapes (so document 's size don't hinder its agility)
Once the erroneous Patterns are deleted, I: 
Duplicate the Pattern one time Hide the Original Pattern Merge the Duplicated Pattern  
Step #5- Create the Tessellation
Duplicate the Merged Pattern enough times so it fills the entire canvas, creating a non-heavy tessellation  
QUESTIONS for:
Steps #1 and #2, is there a more efficient workflow to adjusting the constrained shape sizes, rotating and moving them so one can learn if they fit into both the *Pattern* and *Tessellation* at once? (rather than having to go through both steps).  Ideally, I'd create the Shapes & fill with their corresponding image as usual - but then Adjust, Rotate and Move the Shapes within the Pattern and Tessellation so they snap to eachother in one step.   Also, this more efficient workflow would allow me to skip Step #3 that would have multiple erroneous shape sizes [How] can I use the isometric panel for this? Step #3, is there a different format or method I can use so that the repeated, individual Shapes and Patterns don't reduce the document's agility?  Otherwise, when making modifications the document's large size hinders its speed.  Also, if I don't merge the patterns into images, when returning to the document for any additional modifications, I can avoid having to re-create the tessellation.    
Thank you so much for any feedback or guidance.
 

Thank you, link for reference here
 

Hi there, thank you so much for the tutorial references. I've watched them and they've helped my workflow a lot.
The Isometric panel you referenced looks very relevant to the what I'm trying to achieve. I'm new to this forum but will assume it works similarly to others. Because my new question's topic is quite different (isometric panels and snapping), I am going to begin a new forum question thread.
