How time flies when you spend it with a new baby :) After a wonderful parental leave, I am happy to be back at work this week. And for my first blog post in several weeks, I decided to write about a topic that I think can be a bit confusing sometimes: Real Watercolor Deposition vs. Flow.
When you paint with the new Real Watercolor media in Painter 12, there are actually 2 very distinct painting models happening: deposition and flow.
For instance, in the deposition model, you can control such things as:
For example, in the image below, only the Grain setting was adjusted between the 3 strokes. You can see that the deposited media responds to the grain setting. The pigment concentration of the deposited media folllows the paper pattern. The flow process was paused to capture the image.
Then we let the flow proceed by unpausing the process:
Because the brush used in this example has some granulation in it's flow settings, some grain is visible in the first stroke, even though none was visible after the deposition.
I think this covers the most common settings that control deposition. In a future blog post, I will review what settings control the flow and how they work.
If you have specific questions on the topic of Real Watercolor Deposition, or any other comments let me know :)
Hey Chris...welcome back...'-}}
Thank you very much for continuing to describe the nitty-gritty of how RWC brushes work. It's very, very helpful...
What is the relationship between deposition, flow and the animation step settings?
Is animation step purely visible in that it just displays the flow or does animation step impact in any way the end result of the flow settings? My guess is that it does not impact deposition at all?
PS: you've misspelled "independEnt"...'-}}
thanks for the feedback!
To answer your question, animation step only affects flow "animation speed". It does not change the end result of the flow. And it does not affect deposition.
You can think of it as how much "flow work" you want the system to do between each rendering of the flowing area.
You might for example want an image update after each flow calculation. This would be a very smooth animation, but very slow. This would be setting animation step to the minimum value.
Or, for example, if you use a large step value, a lot of work will be done between each rendering. The result is an animation that will be less smooth, but faster (because less time is spent updating the the current image).
The extreme would be no updates while the system is flowing. This would mean that you would see no intermediate image updates. Just the final dried result. This would not be as interactive because you would not see the paint flowing and drying.
Because every system is different, and because of the various brushes you can create, I decided to include a control for the animation step (speed).
Thanks for the typo catch! I often get that word wrong because of the french spelling ;)
>>animation step only affects flow "animation speed". It does not change the end result of the flow. And it does not affect deposition.
That's what I figured. I tend to set Animation Step to a high value--generally between 7 and 10--primarily because I have an older system and not much RAM (just 2GB).
What would be VERY, VERY cool is if we could STOP the flow rather than just pause it because often, I see something as animation is progressing that I like.
Given your description of the animation process my guess is that it might be tricky to code the Stop Process because it could be what I see on the screen is not in sync with the reality of the behind the scenes rendering process BUT! I could live with that because I figure I could tweak the Animation Step value to a lower number (slower) to "catch" what I see.
Soooo...could you perhaps keep the idea of allowing the user to stop the flow process in the back of your mind??? Pretty please...'-}}

I wondered if that might be what was going on...'-}}
So glad to see you back posting again. I hope you still get plenty of time to enjoy that new baby.
I have had the best time making papers and runny, drippy brushes since your post about using fractal patterns to make paper. The results are truly amazing and I believe mimic traditional watercolor in every way. Changing the brush controls in the middle of a flow is a great help as is the Dry Watercolor Layer command. It is almost as if we are turning and tilting the tablet...and then hitting the paper with a hair dryer. What fun.
Thank you so much for all the work that you have done on Real Watercolors. They are the best.
I completely understand what you mean. Sometimes, you "pause" the watercolor simulation and you would want to keep/dry what you currently are seeing on the document.
There are actually a couple ways to "auto-dry" the watercolor to achieve this. One easy way, as suggested by Skip, is to select the "Dry Watercolor Layer" command under the "Layers" menu. You can even create a custom palette with a button for "Pause" and another for the "Dry Watercolor Layer" command, if you find you would like to use this often.
I have just seen some of the work you have done, and I love it!! I am very very happy to see that you are making amazing artwork with the new Real Watercolor functionality. Please keep sharing.

Hmmm...can I do that when I've Paused? Sounds like I can--given the idea of a custom palette--so I will have to try it...
Thank you so much for the compliment about my work. I hope you and the rest of the Corel Development Team know how appreciative I am...we are...of your efforts. Y'all rock big time.
Excellent article. I understand the Real Watercolor process better now.
You mentioned you could create a button for the Pause, but I was trying to create a custom command and can't find where the pause is in the menus?
you are correct. My mistake. You currently can't add the pause command to a custom palette.
The only way to access it from the property bar or the brush controls panel.
