Summary | 0004206: Transparency display lost on multicolored object when reloading file | ||||
Description | After saving a file, next time it is reloaded display of transparency is sometimes lost on more complicated objects but not the transparency parameter. I have been able to isolate this to a the simple case of an extruded object with multicolored faces where transparency display is always lost on file load. It was tested with latest development version on Win7, but I have experienced these problems for a long time, also in stable ver. 0.18). It was confirmed by two forum member using Windows 10: Link to discussion thread in Help forum | ||||
Steps To Reproduce | 1. Create a simple shape, for instance a rectangle and extrude it. Mark it and apply transparency under the view tab, for instance set it to 80% and observe correct display. Save and close file. Reload it and observe correct display of transparency. 2a. Mark object, right click, Set Colors, mark one of the faces and change color. Keep transparency. Transparency is still correctly displayed. Save file and close it. Reload file. Observe transparency display gone but color is correct, and on inspection the transparency parameter under the view tab is still at 80%. 2b. Close file without saving and reload again (transparency gone). Mark object and change color so that it gets a single color. Transparency is back again. Save file, close and reload. Transparency is now correct. 2c. Close file without saving and reload again (transparency gone). Change transparency (for instance to 81%). Observe correct transparency being displayed again. Save, close and reload. Transparency display is gone again. The attached files show the results of the different tests 2a to 2c above. | ||||
Additional Information | Could the problems be related to this fairly recent change that can allow per face transparency to be set? Link to per face transparency forum thread Forum member wmayer in that thread noted that "The problem might be that the Transparency property was designed to affect the whole object and the possibility to set transparent color per face was added much later. So, it seems that the order of reading in the properties from the project matters." | ||||

Confirmed and set to 0.19 target |

Still present in version 0.19.23141 |

I just tested this and in step 2a I lose the cube's transparency right away (no saving or reloading). As soon as I set a per-face color, all other faces lose their transparency. Though oddly, if I select a face it draws with the correct transparency.

Yes I see that too. In step 2a if transparency for the cube is set before color selection, all but the face where the color is changed looses transparency. However if one of those faces are selected, transparency temporarily comes back, but goes away again when the face is deselected. (no saving or re-loading). |

@DeepSOIC do you have some moments to look at this? Possibly fix before v0.19 release? |
|
@Kunda1 sorry, i don't have FC compile environment set up yet. It's been so since my windows decided to destroy itself somewhere in late october. I will set it up eventually. |
|
I can no longer reproduce, tested in:
@otoien can you please re-test with a recent development build? I believe this has been resolved during the 0.20 development phase. |
|
I am confirming your finding, I can also no longer reproduce it |
