And I hope to change  control point counts, after draw line,, (as future request).

Thank you for your feedback.

when you select multiple dots of lattice in free form pose mode, gizmo doesnt have small ring for move in all directions

Thank you for your feedback.

I really like 3d coat dev working way (try to keep communication for basic user like me) , then just hope 3d coat more user friendly. (I know you are main developer about these new curve tools and thanks you enhance for retopo and modeling room

Then I have some bug? (maybe I think) reports about curve related tools in retopo/modeling room tools.

1.  I can not correctly locate new curve on plane (XY, XZ, YZ)  I tried to use "on plane" option, with set each world XY, XZ, YZ, but even though I set orthographic view , and set plane so, new curve not locate on the world plane. 

2.  when Scene scale not = 1.00,  generated cap (start) change scale but other mesh keep the scale (which decided by Scene scale). then I often need to remove cap only and re-fill it.

About locate/draw new curve on the virtual plane where user intend is my main problem (though I can manipulate each curve point or full transform with gizmo and input location, but I hope to know how you generate new curve on your intend plane like world XY plane strictly.  so if I miss option or usage teach me please if you can. (I believe maybe some other user have same question about "on plane" option) 

I now try to learn all new curve tool usage, then these 2 is current problem for me... (most of other options seems work as I expected, thanks you offer example curve for some tools (auto generate)  so I can try and error without many difficulity. (maybe  I think we may request option, not generate sample curve as future)

I attach google drive link to show the image.. check these please..

Thanks, at first I hope it work for simple world plane with orthographic mode. Or with view , if you can add option which auto locate curve on the current orthographic view. 

I means, when I set Fromt view >>  curve auto generated on the XY plane ..with the options. so we can strictly set curve for modeling then easy use curve tools. (swept gender etc)

At current I often select the curve >> r-click >> then put on world plane for each guide and curves, . but it sometimes change shape (if curve not along with same plane,  put on plane auto project curve on the world plane)

And I do not know how to generate mesh with Surface patch  ^^;;   I made close spline with curve editor. and set the curve ,and set UV counts, I can confrim tool show virtual mesh to check for temp view.   but when I "Apply mesh" it not generate any poligons..    is there any condition to work this tool? 

I got this message "Face deleted due to non manifolded mesh", but I do not think my curve have problem... actually 3d coat show the virtual grid correctly, until I apply it.

When I use a tif image and a tiff image as the texture color and paint it in from camera mode, the color painted is different from the original image color.

In the tiff image, the preview also seems to be wrong, maybe the blue and red are swapped.

[Carlosan]

Is on RBG color space ?

If it is CMYK change it ro RGB.

Hope it help

[kain_ty]

I'm not sure about the color space.
I used an image output from 3DCoat with Depth Along Y.

[Carlosan]

Please explain in detail your current workflow.

Exported Depth images for displacement maps are not used as color images for paint

[jimhatama]

Quick curves menu hotkey got ignored if you enable On Plane with Curves mode  in e-panel

[Silas Merlin]

I think there is definitely a bug with baking of light with reflections.
if you choose "separate paint objects", one of the objects will be black on the baked map :

 

Please test with this file : Test_baking_Light_and_reflections_001.3b


-open file
-go to paint room
-textures menu > light baking tool > light and reflections >> tick the box "separate paint objects"
>bake
result will likely be like in the screenshot above in which the second "T" is entirely black.


This problem also occurs sometimes without ticking "separate paint objects", but I was not able to create a test file that reproduces that yet.

Thank you.

[kain_ty]

Start with Tiled box 3x3 in Surface Sculpting.
In the paint room, paint the circles in red, blue, and yellow, and return to the Sculpt room.
I went back to the Sculpt room, went to the File menu, Export, selected Depth Along Y, checked Save Color, and saved the image.
That's how you loaded the image into the Smart Material.
The file name is _Color.tif, so I think it's a color texture.
The image looks the same in the Windows preview as it did in 3DCoat.

I was testing it and you are right, the color painted is different from the original image color

Thanks for point it up.

As workaround export color as another file format as bmp or png

//edit

fixed on latest version .36

Fixed

Not sure if it was mentioned but Retopo via decimation is not working. No dialog will pop up to select density and it will just go straight to decimation but shows bad results.

[Carlosan]

-> On 2021.34 is working fine.

Please give a try

Hope the software can automatically convert the correct result. In addition, when the AMD multi-core processor is working, the multi-core data processing method is not as fast as the single-core data processing speed, and it is hoped that it can be optimized.

Latest version on 22.08, version 34.

If it will happen, please drop me the scene, it keeps the camera position, then, probably, I may reproduce it.

After adjusting the mode, you cannot return to the original move, rotate, and zoom， See the video for details

Thanks, now undestood.

[Silas Merlin]

baking light and reflections does not take emissive into consideration.

Is it because  :
-It just was not implemented that way ?
-when you switch to paint room, render room settings are lost (screenspace reflections get ticked off for instance) ? (or are the render room settings lost not when you leave the room but when you return to it ?)

 

asking again since there was no answer

Are there plans to implement point lights and spot lights in render room, or is that already possible with the mysterious nodes that apparently noone knows how to use ?
 

[Silas Merlin]

I think I read in the notes that light baking was implemented for sculpt objects ?

Here is a test with painted sculpt objects in the render room :

 

And here is what happens when you go to paint room and bake light with reflections :

Here is the file to do the test. you have to match the render room settings yourself, since they do not get saved :

Start_001.3b

[kain_ty]

.35
The preview of the stencil seems to be different from the actual area of the stencil, the display of the from camera is also wrong, and the image is only displayed in the upper left corner when in tile mode.
Also, when using smart materials and stencils together, roughness, metalness, and depth are ignored by the stencil. Only the colors are properly clipped by the stencil.

[Tubor]

In version 35, there are also symmetry and invalid seals. Turn on the subdivision after symmetry, and sometimes there will be a bug that causes it to not be displayed. Hope it can be resolved in time. See the video for details。

Windows version 2021.35

The strokes tool when importing for "Perform Retopology" still not working.  Regular Stroke tool and Smart Retopo.

[kt2]

The 'Align Vertices' tool in the Modeling room ignores Z-Up coordinate system set in the Preferences.

Send, please file

[kt2]

Shortcut binding doesn't work correctly for the mesh display settings in the drop-down menu in the Modeling room.

Example in the video:
1. I associate an Alt-W shortcut with the 'Retopo Wireframe' option from the menu
2. I press the shortcut once in the main 3D window, nothing happens.
3. Once Alt-W is pressed near enough the drop-down menu, the whole drop-down menu opens.

So Alt-W doesn't operate as a wireframe on/off toggle, but instead works as a callout for the drop-down menu to unroll.

Send, please file

Windows version: 2021.35

File sent. Simple file. I exported the default creature. Closed 3DC. Opened 3DC and then imported the model for Perform Retopology. 

First Problem. The Perform Retopology tool tip states that the model will be imported into the Retopo Room but the model is imported to the paint room. You have to switch to the Retopo  Room.  Test importing an external model to see this problem.  The file I sent the model is already in the retopo room because I saved the file with the creature in the Retopo Room.

Second Problem. Once in the Retopo Room, the Stroke tool starting in a open spot in the viewport (red stroke) and drawing the stroke across the model does not work.

Starting a draw stroke on the model works. The green stroke is there.

Currently, the 3DCoat can only make sections for sculpting meshes.

So, you imported mesh as retopo mesh, not as the reference?
