Gradient Fill

14 posts in this topic

Hi there, i been doing some terrain tests and it seems the gradient fill tool is still not working. (V 4.7.36)

It shows it how it should be in the smart window but when you apply it there's no gradient as such. (just the two colors without the blend)

It works if i just create a new scene cube from scratch and fill it.

Just when i import a mesh either ply or obj.

 

Oh also the icon for the material get corrupt when i edit the values (oldschool paint)

Should i use oldschool paint if I want to just paint the vertex colors?

 

I also have a feature request, theres a similar one on trello but it would be nice if you moused over the layer blend text you could press the up and down keys to cycle through the blend modes.

(like photoshop)

 

I would of posted this in the new release/beta thread but i am unable too.

 

Cheers

Royston

Your model has a UV map?

Or are you painting an imported model in Sulpture Room > Surface mode ?

I used the import object to vertex paint option.

I did the UV,s in blender. Used the displacement modifier on a 1024*1024 grid.

If im vertex painting though this should not matter?

I think its surface mode yeah.

Im importing it as a ply into toolbag with just vertex color no texture.

Use Vertex Paint when you want to paint mesh without UV mapping it.

Try Paint UV mapped mesh option.

I think that Royston imported for vertex painting.

Vertex painting:

In the paint room, here is my result shown in Flat shade... The Gradient appears to be working in 4.7.36. 

I do not go by the preview window as is seems not so accurate.  I do just color gradient filling ( no depth / no glossness) by adjusting the distance of the balls till I see I get what I want. Depth is not supported in the paint room while painting in vertex mode. All details have to be in the surface mode model in the sculpt room.

Check in Flat shade, then at that point I do real work once I am  happy and I switch back to Smooth Shade under the View Menu.

Side Note: no smart material used.

I think its something to do with scale why its not working.

If I create a new mesh or load a smaller one it works as intended. When I load these big terrains I been saving out its not working.

It looks right in the smart material view but when you press enter to fill layer its not doing it the same. I tried filling the object aswell but that does nothing.

I've attached a test file so you can check it.

Is there any chance in the future that the smart view will go? Just have the program WYSIWYG?

Out of town but will look at your object when I get back.

I do not know if this is what you are asking for but here it is. I do not use gradient fill much so it took a little testing.

First do not use the Smart Material Preview window, it is inaccurate. 

Orthographic Mode.

Depending upon the scale of the model, you have to adjust the spheres. 

Zero out all the axis. Now only use the Y axis by manually typing in your setting, the two spheres in Y space. Both negative and positive. 

Depending upon the scale of your object the settings can get quite large look at my picture.

Y positive is 15,000

Y negative is -100

Your numbers could vary depending upon your need. 

I put a cheap noise on the terrain for better viewing. 

Picture shows the result in perspective mode

I tried updating my graphics drivers, re-installing 3dcoat and deleting the leftover folders in my documents.

The smart material view shows it how it should be. When i press fill layer its not filling the same.

I do the same as you, its just not giving me the same output.

Here's a video you will see.

Here's another example using a different object. It does look like it's something to do with scale, but the smart preview shows it how it should be.

Beta 4.7.36

Here is your model imported the same way as shown in your first video. Smart Material Preview is not used. ATM it is not accurate. Andrew will have to look at it. Remember I said not to use the Smart Material Preview.

Scale of the object does matter for your gradient settings.

Picture shows my gradient settings that work. Yes on each object you will have to play with the gradient settings a little to get the gradient as you need it. Filling temporary colors is fast  though to test your gradient settings. Of course set the gradient settings point 1 and point 2 to your desired settings but remember it is effected by the scale of your object.

I did watch the grad_hb.mp4. and  the other video has well Then used your the steps for importing the model through vertex painting as shown in the first video... 

My settings are shown in the picture I put in my last post.  

The gradient was filled correclty between the two colors chosen. Look at my settings and do not use the smart material preview... 

There is no more I can give you on this matter. If I have time I will make a video over the weekend.
