Need to apply a fix for negative values - eg, 'x/-5'

Spotted a problem with the mathematical precedence of * and / and + and -. For now can work around it by adding brackets to explicitly specify the correct precedence.

I have a blender fluid simulation explosion. I've opened the python script unity_6way.py in the "Scripting" tab. When I press the run script button, no errors appear.

Now if I look for this tab, that you see in the Unity VFX 6Way lighting talk

I dont see where the 6-Way lighting dropdown is?

Im looking for an explanation on how to use this amazing resource! Please note I dont have much experience with blender.

At Blender version 2.83 the various texture nodes have a 'Dimension' input for 1D, 2D, 3D, 4D. This results in a new 'W' input which is sometimes hidden and sometimes used. The presence of the additional input means that the Scale input from an expression is being applied to the wrong input and the other arguments are being shifted one socket out of place. Need to amend the linking of nodes to handle the additional input socket.

Input variables are positioned based on the sequence they are encountered in the equation - would be good to be able to automatically resequence them - eg alphabetically all short ones followed by alphabetically all ‘longer’ ones.

Currently, the add-on only caters for smoke stored in Point Cache files. It's come to light that it's possible to extract smoke information directly from the smoke domain modifier and this is preferable for many reasons - in particular since it doesn't require parsing the saved Point Cache files, and so it will no longer be restricted to that format. Also, it should be more efficient and will also make it work with later Blender versions (which now use Mantaflow and no longer store data as Point Cache by default).

Operator popup is not being shown when triggered via the Shift+A shortcut.

Need to update the documentation pages for Particles to Path and Blend Vertex Colors and remove unnecessary detail from the 'readme' since the Wiki now covers this.

Problems with compatibility with Blender 2.82 (appears to work fine with 2.81)

1. Hexagon preset fails due to IndexError: bpy_prop_collection[index]: index 3 out of range, size 3
2. 'min(x,y,z)' failing to link the 'z' input to the internal nodes

I suspect this could be related to the enhanced Maths node with additional features and auto-show/hide of input nodes based on expression.

Particles To Path add-on needs to add the operator to the Add menu.

Hi thanks for making this! I was having trouble getting the button to show up in the F3/Spacebar menu on Blender 3.1

version 2.03-beta_2022-11-24 (downloaded from Blendermarket)
Blender version 3.2.2 stable, 3.3.3 LTS, 3.6.3 stable, 4.0 stable, 4.1 (alpha) - not checked with other versions, that's just what I have lying around.

The version being distributed here seems to be a little wibbly. It includes the prompt screen saying its the free version, and does not offer to create a new expression from a script (although if I write a script and input TEXT:(name of script) it works as expected).

The Edit window (as seen in the documentation) also isn't appearing
Examples from documentation to indicate what I mean:

Maths Expressio add-on throws an exception and loses the internal nodes when a blank expression is added. Also, would be good to provide option to keep orphaned input/output variables instead of losing the links when an expression is made temporarily invalid while editing.

Update Blend Vertex Colors for compatibility with Blender 2.8.

It's available on blendermarket now,but I don't have us paypal account(it's not convenient in my country).
Do you plan to release it later?

Hi,
Do you plan to update your addons for blender 2.8?

It says in the code this when trying to utilize it

AttributeError: 'IndentationError' object has no attribute 'msg'
Error: Python script failed, check the message in the system console

i don't know what that means

Dynamic Maths Expressions (Paid version) hasn't survived the change to 4.0 unscathed.
If I try to create an instance of the Test script, it creates an empty geometry group with no inputs or outputs, and the status bar shows the following error:

Build of node tree failed : 'GeometryNodeTree' object has no attribute 'outputs'

while the console shows
