Tips and Tricks   

Object manipulation

RENDERlights divides 3d objects in two categories, static and dynamic. In order to manipulate objects you first need to convert an static object to dynamic.

This is a simple operation you only need to check the box dynamic in object Model panel.

Dynamic objects can be moved,rotated and scaled on all 3 axis.

Click the center icon to change the mode, and use the axis icons to move, rotate or scale as needed.


Tips on returning to scene if you get lost.

Best practice is to save some camera views on advance, we have an array of 10 camera views that can be saved to the numbers from 1 to 10 or 0. Simply select a nice angle and press a combination of alt+a number, and that specific view will be saved.

To recall that view just simple press the number and it will take you there automatically, to record a new view on the same number position repeat the process of saving with alt+ a numebr form 1 to 0.

Another way is to use gravity, if your model seems to be too far away, just activate gravity option by pressing the letter (G), this will cause you to fall from heaven and re-spawn back to the model on a random position.


By pressing the letter (G) you will drop to the ground and you will collided with objects, to cross trough walls or doors just use the wheel on the mouse. Reduce speed by using the + or - keys on the keyboard.

Note: Panning is not possible when gravity is on.

Some times you will be requested to inform the measures of certain objects or distances on a scene, press the (M) key to activate measuring tool, click on a

vertice or end point and follow the red line till you reach the next end point or vertice.  Measuring can also be activated under settings/ scene/ measuring.

You can select metric or imperial units from there.

Water Caustics effect

Real-time caustics is a very complex procedure, it is hard to find an engine that could do such an effect, but RENDERLights is able to do quite a convincing job.

To create the illusion of a caustic water effect that comes from a swimming pool or a fountain, we could do a couple tricks.

Create a video clip containing the ripples of a real caustic effect, then use it in collaboration with a Spot Light, by applying it to the texture slot. This will project the video to any wall or surface generating the desired effect.

Alternative to this, use the same video clip and apply it to the water surface on the transparency slot material. then use any standard light

(spot, omni) underneath the water pointing upwards. The transparency on the water material will create the shadows that then will be reflected to the walls around.

How can I speed up my virtual presentation

A few things are recommended in order for a virtual presentation to work faster.

1) Keep fewer objects on a scene, if you have same material keep all the elements either grouped or welded by material.

2) Multiple layers of transparency reduces the speed of a scene, change from 24bits to 8 bits RGB transparency blending, in the scene/render materials option window.

3) Water effects are very nice, but if you have a really large scene it may slow down the system, use the water and bloom effect wisely.

4) Better hardware always helps, so a good video card with 500mb video memory or more will give you a better results.
