HDRi Projected

HDRI PROJECTED: When active creates a DOME where the background is projected.The dome can be adjusted through several controls. Furthermore allows to apply the background to almost any object.

MOVE X , MOVE Y and HEIGHT: These controls allow to move the dome through the three axes. Height is useful if you want to make a small correction of the height of the background. NOTE: Do not exceed with this value, as it will deform the background

DOME SIZE: Allows to resize the dome dimension

TOP LIGHT: Regulates the light intensity and fixes issues as reported in the next page.

SMOOTH WRAP: Object wrapping sometimes present unwanted edges. Increasing this feature‘s value the wrapping results softened

WRAP and UNWRAP: WRAP connects a selected object to the bottom of the HDRi Projection Dome (Ground)

ADD GROUND/REMOVE : ADD GROUND has been created to apply the active background to any object in the scene. As explained in the next page, you can apply the background even to an additional landscape (A.N.T. Landscape add on) and resize it, move it perfectly merged within the whole context . REMOVE: Removes the applied background.

HDR and Dome Light

TOP LIGHT: Regulating this light in combination with HDRi Light, helps fixing lighting issue that can surge using HDRi Projected since the dome receives light form different sources

HDRi LIGHT: Adjust the background light, then it will affect the scene by illuminating + or – the objects in it. (It is suggested not to exceed the value 2 for a good yield)

Refers to a standard display of the HDRi projection. As seen there’s a lighting issue that can be easily fixed as shown in image 2 and 3.

Image 1

Regulating Top Light + HDRi Light the image can be brighten solving the lighting issue

Image 2

As well as Image 2, regulating Top Light + HDRi Light the image can be darken solving the lighting issue

Wrap Features

Wrap Buttons:

STEP 1: Create a Mesh (Plane) as in FIG.1

STEP 2: Keep the Object active and select the WRAP Feature. Automatically the Object will connect to the DOME Ground. (FIG.2)

STEP 3: Move the object and the terrain wrapped to it will follow in any direction you move. It is especially intended to move on the Z-Axis allowing to create any kind of ground depression. (FIG.3) The object is visible and clicking on the Hide button it will

STEP 4: In (FIG.3) the object is visible and by clicking on the Hide button it will disappear as shown in FIG.

NOTE: The UNWRAP Feature releases the object from being attached to the DOME ground

FIG.5: In this figure are indicated the Plane Mesh to which is wrapped the terrain and above it there is a Second Plane Mesh that we created in HDRi. Using the EXTREME PBR Add-on, to the Second plane mesh, we applied a WATER material.

FIG.6: Being, the Second Plane Mesh, underneath the ground level, it generates a water filling effect in the ground depression created by the Plane Mesh originally wrapped. Selecting the Second Plane Mesh in the Outliner, by clicking HIDE within the HDRI Background projection menu, the water effect can be hidden or seen in the scene.

FIG.7 & FIG.8: If for example you add to your scene an object such a landscape created with the A.N.T. Landscape Add-on (FIG.7), by clicking the Ground button, having the object selected, the background is automatically applied as seen in FIG.8. Using the Remove button will remove it from the selected object.

Fog Menu

SHOW FOG: Check it to make the Fog appear as shown in FIG.2.

DENSITY: The lower the value the thinner the Fog (Value can go from Min ”0” to Max “2”)

LEVEL: Increases the height of the Fog. From just above the ground towards the sky when the Flip Top condition is unchecked

EMISSIVE: While using Eevee the emissive feature brightens the fog but doesn’t emit light. On the other hand in Cycles, when the Emissive value is increased, the Fog acts as a light source.

PATCHES: Creates empty spaces in Fog flow. The higher the value, the scattered the Fog.

P. SCALE: Increasing this value, causes the Patches to be bigger, scattering the Fog even more.

WIND FORCE: The higher the value, the faster the Fog displacement

DIRECTION: Like on a compass the direction can be rotated over 360°. Negative values invert the flowing of the Fog

The FOG Menu is an important feature that allows you to control its condition within a particular weather situation. Once you check its box, the FOG Menu unfolds. It is composed by several controls that has been set to give an optimized surrounding. It is up to you changing them to meet the conditions that suits what you are looking for.

FIG. 1
FIG. 2

MATERIAL PREVIEW MODE: Using this view mode it’s easier to check the Fog condition. In the upper image the Flip Top is active and the Fog direction is from Top to Bottom. In the lower image Flip Top is unchecked and the Patches have been increased causing the Fog to scatter. P.Scale also if increased, causes the Fog to produce bigger empty spaces (Patches).

FLIP TOP: Inverts the Fog original position. Instead of going from Bottom to Top, switches it from Top to Bottom. As seen in Fig.A

FOG DETAILS: Expands a menu allowing to choose among several options going from Very Low to Best. The Original position is named Default. Fog Details relate with the Render Properties in Blender (Volumetrics in Eevee) & (Volume in Cycles). For instance in Eevee the Very Low position acts on a Tile Size of 16px and 8 Samples while in the Best position the Tile Size drops to 2px ane the number of Samples increases to 128. On the other hand in Cycles the Very Low acts on 2 Max Steps while in Best the Max Steps is 128. This features has to be used carefully since the performance is seriously affected both from the quality requested as well as the machine you are using. (Rendering Time)

Use A.N.T. Landscape

HDRi TO OBJ using A.N.T. Landscape add-on

(*A.N.T. Landscape does not need to be dowloaded since it’s already available in the Blender Add-ons)

In the preferences menu select:

Add-ons

and in the

search window

look for A.N.T.Landscape.
Once you found it,

activate the check box

and

Save Preferences.

Now you have the Add-on running.


With A.N.T.Landscape you can generate a landscape and adjust it to your needs. Position it wherever needed.

With the created object selected, click ADD GROUND and the selected terrain background’s material will be applied deforming it exactly accordingly to the object position.

Furthermore you can displace the object adjusting it as requiered and the applied material will follow exactly every change.
