Photocentric Studio Changelog

Release 1.2.99 (04-03-2026)

Download Software 

• Rewritten the support object classes from the ground up. With the following improved points:
  • Mesh geometry (spheres/cylinders etc.) is not generated anymore during supporting. Instead, it lives only 1x on the gpu. This is much faster, less memory etc.. 
  • Reduces a lot of the supporting algorithm time and removes any lag you might experience in dragging/modifying supports.
    1. and allows for bigger models with editable supports.
  • There are more distinct types of beams now. i.e.: 
  • a vertical pole; which if clicked highlights all affected shores/beams. Reshores if you move it. 
  • diagonal shores; currently rectangular to provide extra vertical stiffness in printing 

• Rewritten the placement of manual supports. 

1. Previously when you would place a single support it would live as 1 object in the object tree. So a part could have 100 single supports. This is now all unified in 1 support structure object. For the simple reason people abused it and had 1000’s of single supports. 
2. You can still add any of the manual supports; with settings as predefined. But under the hood they are joined with the main support object.
3. The advantage here is that if you place a tree or single support, it allows the algorithm to place shores as well to the main structure (independent of type of placed item) 
4. The downside if you can’t easily delete 1 item anymore from the tree. But you can still click the main pole and press delete. It will delete all affected parts.
5. Make sure to put the live preview on to see the support preview when placing manual supports. So you see the live preview (that is also new and consistent now) 

• Editing the support

• As all supports for 1 part are now joined into 1 object editing is also unified. Right click and ‘edit support’ to edit a support. 
• You can change the values and they will update right away in the 3d view. 
• To edit an entire support; just mark the checkbox. 
• You can still hold CTRL to select multiple sub parts of a support structure. 
• The edit tool will show you what you are about to edit with amounts. 
• New pro Lattice supports now fully editable 

• The auto support algorithm, 

• Also here I went from the start through the entire algorithm to implement this new structure. 
• The intersections should now be prevented. 
• There is now more offset between the part and the vertical beams; by default 1.5* diameter. This scales very badly with the distance; as the signed distance field calculation scale to the power 3. So I would rather make this smaller than larger. 
• The path finding algorithm for finding a suitable location for a vertical pole is also rewritten. It now looks in a cone shaped area downward; with different lengths of the first beam. So when it finds a pole straight down to the platform; with a bit longer first beam than the defined parameter; it does that. Avoiding unnecessary internal support. 
• Overall, if no solution is found; it doesn’t place a support instead of an intersecting one. 
• Many different sampling strategies added (offset, hexagon etc.) 

• Other UI changes

• If you look from the bottom up; it will automatically hide the entire structure so you can see the first beam (tip) of the support structure. 
• You can also toggle this with the support view mode. 
• Parts that have a support structure can’t be rotated in X/Y axis and moved in z axis anymore.
• Better detailed images for large lattice
