Brycetech: Plop Goes the Easel


Download the PDF of this tutorial.

How many times have you rendered a scene just to see a major flaw within it such as an object floating, a hole that shouldn't be there, a really bad texture?   Here is a function that can aid in finding those errors.  It can also help reduce time and effort while perfecting your images.  This tutorial will focus on the use of the "Plop Render" function in Bryce. 

While here, you will learn not only what it is, how to use it and some of its basic features, but you will also see one of the features of the plop render that many do not know exists.  This is a "must see" for those who render in large resolutions. 


What is plop render? 

This is a term which represents a marqueed selection of a rendered image.   Selections appear to be "plop" forward with drop shadows and rendering controls.  This little window will appear as if an easel has been placed on your image.  This feature can be enabled, disabled, or hidden. Use it to help perfect placement of objects, materials or lighting.

How do you use plop render?

Ensure the plop render mode is enabled by checking the plop render control to the right of the main render window. 

 

 

When it is enabled the control will be red; when disabled, it will be white.

Start a render then stop it by pressing a key or clicking the mouse.  (If you desire you can let the render finish.)  Then simply draw a marquee on the image.  (A marquee is drawn by holding down the left button of the mouse and dragging it over the desired area, then releasing the button.)

A separate set of render controls will appear which are similar to the existing render controls, except these controls are for the plop render.

Notice how the plop render window appears to be in front of the image.

The top button starts a render of this plop window. plopren.jpg (1796 bytes)
The second area resumes a render of the plop window. plopresume.jpg (1613 bytes)
The small triangle beneath indicates a popup menu.  Upon clicking this triangle, you will be presented the options to Zoom to Selection; Collapse Selection and Hide Selection. plopselections.jpg (1852 bytes)
Zoom to selection:  If you have marqueed a portion of the scene and select this option from the popup menu, the camera will zoom in to this area and fill the render window with this portion of the scene.   This is excellent for close-ups of objects you wish to emphasize in additional images.
Hide Selection and Collapse Selection: remove the marquee from the image.

Plop Render in Action

While rendering an image, you may need to determine placement of objects or other features quickly.   Due to the complexity of some elements in your scene, you may not want to waste time rendering them.   You may only want to render portions to verify placement and texture.  So start the render and then stop it. plopwin3.jpg (8866 bytes)
Marquee the area that is over the area you are interested in and then start a plop render.  When this plop render completes, it will help ensure proper placement of the objects with a minimum amount of time.

 

  • This same procedure can be used to check textures, placement, and lighting of selected areas in your scene.  It is invaluable for saving time while adding details.

Advanced Plop Render

What are some additional uses for this feature?  

Let's assume you have rendered an image, but you notice a problem in the image.

Notice the center box is floating.  This is obviously unnatural.

You can fix the problem. Save your camera position then land the object.

Go back to your saved camera position.

Then make the image visible again by clicking the display control.

Now all that is necessary is to draw a marquee around the problem area and render the plop window. 

Select the "Collapse Selection" option from the options available from the menu when you click the small triangle beneath the controls.

This image can then be exported in full!  Imagine the time this can save on some of those intensive renders!

How many times have you created a large resolution image and wanted to watch the whole thing occur?  Bryce is stubborn about displaying the entire render while it's happening if the render is larger than the render window.   Below are instructions to work around Bryce's default display while rendering high resolution images.
  • While creating some images, I make several QTVR panoramic renders to help me place the objects and identify dead space.  I want these renders to be quick and effective, therefore I turn off the textures.
  • This step is not necessary for this function. This part is mentioned simply as an explanation for the appearance of the upcoming preview image.
ploptex.jpg (2027 bytes)
These panoramic renders are much larger than my monitor can display, however sometimes I want to see the whole render at one time while it occurs.  Bryce defaults to a "zoomed in" preview, this preview only shows a corner of the render which is not what I want. 
However, the plop render option solved my problem.  I simply start the render and stop it.
  • For best results for this method , it's best to let the render bar make one complete pass before stopping the render (however this isn't necessary).
Now that I have the first pass of the render, I enable the quick preview mode.
  • This step is not necessary for this function.  This part is mentioned simply as an explanation for the appearance of the upcoming preview image.

Without removing the display of the render that has started, "Zoom out" from the image by clicking the zoom controls to the right of the render window.

This will zoom away from the image that had started rendering.  Eventually, the large resolution pre-render is fully visible in the render window. plopwin1.jpg (39805 bytes)
Drag a marquee around the entire preview to select it all...notice that the plop render controls appear. Click the render button on the plop window and you can watch the entire render take place!  Using this feature to help render large resolution QTVR images has saved has me countless hours while making scenes because errors were quickly visible!

Note:

  • I selected the quick preview mode, however you do not have to do this if you do not wish to.
  • QTVR renders incorporate a distortion in the image necessary to make the QTVR work properly. This is why the image is distorted.
  • You can use this feature to render any image, it is not just for QTVR images.

For Bryce 3D only (this function does not work in Bryce4)

Hey, ever wanted to render just part of your scene as an animation? Plop render allows you to animate just part of the scene and render only that part!  Simply render the first frame (click render).   Once the first frame is rendered,  marquee the area that will be animated and the plop window will appear.  Now go to "file" and "render animation" and ONLY the plop window will render in animation mode.   You just GOTTA love that!


Troubleshooting

  • I can't see the render bar.
  • I can't tell that Bryce is rendering
  • Since you have zoomed out, the render bar will be very small therefore it may be invisible to your eye. 
  • Occasionally the render button does not turn red when you select it. 

You can check to see that Bryce is actually rendering by moving your mouse's cursor over any of the visible controls to the left or above the scene (...do not click).  If Bryce does not update the explanation of the control (beneath the main render buttons), it is rendering. If you see an update to this area, you need to click the resume render button for the plop window.

Site Note:

What did you learn here?  Hopefully you now know how to use the "Plop Render" control.  You know how to activate it, and what the basic features are.  You also were introduced to the ability to disable textures and to the quick preview mode.  All of these can save time while perfecting the scene's lighting, materials, and object placement before performing a final render.

You were also shown how to use this simple "Plop Render" function to display a large resolution image while it is rendering. 

By simply:

  1. Starting the render
  2. Stopping the render
  3. Zooming out
  4. Drawing a marquee over the entire image
  5. and clicking the render plop window control

you can watch it all happen.

You can try just to click "resume" to see if the whole thing will just resume the render.  This may work, it may not!

This should be invaluable to those who like to watch Bryce render large resolution images.  However, one thing to keep in mind if you use it for this purpose.  Large images eat RAM!   Forcing a large render to display can not only be RAM intensive, but it can slow the render process because your computer's processor must now update the monitor display as well as render the image.

Have fun!

This is not meant to be an all inclusive instruction on every possible way to have made the final image or produce the desired results.  Bryce offers zillions of wonderful ways to replicate, multireplicate, reposition, etc.  in its powerful interface. Experiment!
